1. Introduction to Excel

The classic ‘Excel Assignment Help’ introduction! This should be the starting point with any assignment or tutorial which is based on Microsoft Excel. So, let’s take the introduction from our assignment help guide and learn what it is exactly. Excel is a powerful and most popular tool which is helpful in analyzing and visualizing the data. It has various in-built functions which ultimately made the task easier for the user. This user-friendly tool can be helpful in creating variety of different type of report in just few clicks and filters. These reports can be exported into Word, PowerPoint, PDF, and other different types of formats. That is why Excel is so much important for everyone to know about it and how to use its all functions correctly. As it’s clear, before start working with Excel, we have to open a spreadsheet software and then we have to do some kind of preliminary tasks, such as saving the file, creating a new file, and building and design the excel sheet for our work. In the beginning, the first thing we have to do is check. We have to check the software which is installed in our system, either it has Microsoft Excel 2010, Microsoft Excel 2013, Microsoft Excel 2016, or availed the opportunities of Microsoft Office 365. Also, check the Operating System. The operating system can be Windows 7, Windows 8, Windows 10, or any other. After that, check whether we are working with 32-bit or 64-bit version. Then open the Excel by clicking on the start button, clicking on the Microsoft office or Microsoft Excel, and finally double-click the Excel icon. In case of error, contact software support system. Well, yes, this is the typical step to just open a new file in Excel, but no data will be stored in data file at this particular moment. The start menu can be accessed by clicking on the windows button and then we have to find Excel. However, for Windows 8 and 10, we have to click on our windows button or icon and we have to swipe between our app screen and start to find Excel for this particular assignment on help. We can also pin Excel to start using with a right-click. After that, we have to pin it to the start and we can find Excel tile in the start window on the desktop. And now, what do you think the start window is gone? Well, we have another easy option to open Excel and new file by clicking the File icon right on the task bar. It will instantly open the Microsoft Excel. Now, in Excel 2010 and Excel 2013, this window is known as the “Windows”, and we have to look at the options to open file and create a new file. But in Excel 2016, the start window doesn’t exist anymore. Instead of the start window, it consists of the “Recent” tab where the recent file will be shown, the “One Drive” tab, and the “Computer” tab on the left hand side. Finally, data files can be stored in different types of data sources and the connection string can be used. We can import and export the data between Excel and other database, such as SQL server. So, the import and export functionality in Excel will help us to formulate, analyze and visualize the data with the help of charts, diagrams, and predictive findings. Well, that’s all for the introduction to Excel. The next lesson will be saved and save as the Excel file in appropriate folders. This is important to keep in mind where we want to store the file because it can be tricky to find the file back. So, stay with our experts’ team on getting further help. So, this is the flawless introduction given for the “Excel Assignment Help” guide.

2. Basic Functions and Formulas

When using Excel for data analysis, it’s likely that we are going to use the basic arithmetic operations of addition, subtraction, multiplication, and division. The good news is that the basic operations are really straightforward, but we need to know about the order of operations (BODMAS). The order of operations is the order in which Excel carries out the calculations. In this case, Excel would carry out, for example, first, anything in brackets; second, any indices (i.e. powers and square roots); third, any multiplication and division from left to right; fourth, any addition and subtraction from left to right. Please remember that Excel is a “computation” grid and that, for example, in a column of cells, if you want Excel to compute something in each of the cells, then the same operation must be written in each cell in the column. Also, remember that when data is entered, it sometimes needs to be converted by Excel from text to numbers when it may be seen as text only. For example, “=B5*1” would identify any number in the cell B5 and multiply it by 1. However, if B5 had been left by Excel as text (e.g. it had been brought in from another source and not recognized as a number), then the answer to this would be the contents of B5, with a comment in the cell indicating that the contents need to be changed from text to numbers. Different data would give different results when multiplied by 1 using the “fill handle”; the selected cells are the ones that will be completing the operation. Use these tips to write your own assignment in an Excel file and remember that the best way to learn something is practice!

3. Advanced Data Analysis Techniques

The average and standard deviation are both measures of spread in a data set. However, the standard deviation is a measure of the dispersion or variation in a distribution, while the average is a measure of the central tendency of the population. When we calculate the average, the value of the individual data points is taken into account. This means that a change in the value of any given data point will impact the average and hence the central tendency. Excel has a number of tools that can be used to check whether a data set is normally distributed. Also known as the bell curve, the normal distribution is a mathematical function that describes the way values are distributed. The diagram and output of the normality test provides a good way to check for normality. Next we come to the rank and percentile tools in Excel. The rank tool is useful for working out the position of a particular value in an ascending set of values. The percent change is useful for the evaluation of profitability over multiple periods of time. It is a standard statistical measure that indicates relative change over time. This is often valuable in financial applications, for example assessing stock market performance from year to year. As shown above, calculating the percentage change for the profits from 2017 to 2018 results in an increase of 33.33%, which is a healthy return. This type of analysis can also be used in fields such as marketing when comparing sales figures from one period to the next. Last but not least, we explore pivot tables. Pivot tables are used to summarize and reorganize data from an Excel spreadsheet. By definition, pivot tables are data summarization tools that are used in spreadsheet programs such as Excel. It enables the quick analysis of large amounts of data as well as the ability to compare pieces of data in a number of different ways. Pivot tables can be used to create histograms, since they allow for the grouping of data in any number of ways. From the data menu in Excel, select data analysis and then histogram. First, select the input range, which in this case is the set of data that has been used to create lists and charts. Then put the output range in the location where the histogram will be drawn and then create the bin range. There is a tick box for chart output, which brings up a further box that asks for the location of the histogram. By selecting a suitable cell, the histogram will be produced from the data. Finally, the output range must be selected. Like R, Excel is able to produce sorted lists and obtain their corresponding ranks. The RAND function is used to fill a set of cells with random numbers, which can bring about fantastic applications in terms of computer simulations and gaming projects. Overall, the facilities that Excel has for statistical computations make it an ideal software package for anything involving data, especially if there is a substantial mathematical content. Excel is capable of aiding in the performance of regression analysis and statistical tests, as well as a large number of complex mathematical calculations. Excel really does provide a notable and practical service to all of the scientific and engineering communities on a global scale, providing straightforward tools for these complex investigations.

4. Data Visualization in Excel

Data visualization brings life to the numbers and as the saying goes ‘a picture is worth a thousand words’. In Excel, you can create visual representations of data to enhance the understanding of the data. One of the most popular data visualization features in Excel is the creation of sparklines. Sparklines are tiny charts that fit in a cell and provide visual representation of data. They are simple and convey the trends and variations by showing the data in the form of line, column or win/loss chart. To insert a sparkline in the sheet, go to the ‘Insert’ tab in the ribbon and select the type of sparkline preferred. You must provide the location of the data and the location of the sparkline. It is a requirement to select an empty cell where the sparkline needs to be placed. After creating the sparkline, ‘Design’ tab in ‘Sparkline Tools’ is useful where types can be changed as well as axis can be customized. The range of the axis can be specified as well as one can choose if the high, low points or the negative points should be highlighted. In the same ‘Design’ tab, there is a group where sparkline color can be altered and the marker color as well as the axis color can be specified. Secondly, Conditional formatting feature in Excel is a powerful and easy-to-use feature that enables the users to visually display the data based on the specified criteria. With the help of data bars, the data in a range of cells can be visually represented and highlight the higher and lower values. This is useful when someone wants to differentiate between high, medium and low values of a data range. Many times, a user is required to create multiple charts with similar data range. With the new feature called ‘Recommended Charts’ in Excel 2013, the user can quickly display the most suitable charts and create a chart that best illustrates the data’s meaning. When the user highlights the data range of interest for the chart, the quick analysis button appears at the bottom right hand corner of the highlighted data. After clicking on the button, a menu will appear showing the options of ‘Recommended Charts’, ‘Total’, ‘Table’ and ‘Sparklines’. By selecting the first option, a new window of insert chart will appear with all the recommended charts that are best suited for the data. This will save the time and effort of hovering over each chart type and seeing if it suits the data. Lastly, Excel also provides the feature of creating a ‘Pivot Chart’ which is based on the data of a ‘Pivot Table’. Pivot charts are used to graphically represent the data of a pivot table in the form of chart or graph.

5. Tips and Tricks for Excel Efficiency

With a few tips and tricks, you can increase the productivity and efficiency of your work in Excel, whether that is making a complex formula, creating a dynamic chart, or finding the fastest way to do something. Avoid use of merge and center (unnecessarily), as it adds extra memory to your file and also can cause your file to slow down. Press Ctrl + Enter to fill data in a series instantly. This will save you the time and struggle of trying to drag a cell’s corner to complete the series. Excel will automatically fill in the cells you select with the appropriate type of data format (date, currency, fraction, etc.), according to the first cell in your selection. Double clicking a cell with a formula in the formula bar will allow you to edit that formula more easily and precisely. If your work requires you to repeat the same block of touch many times over, consider using the macro feature. Create short script that automates the process, and then assign a shortcut key to that macro and use it whenever you need it. Tired of having to select out all the filtered cells before you can do anything to them? By adding the icon to the toolbar and you will have a ‘select visible cells’ button that does it for you when you need to. Work on a second monitor if you have the ability. The extra viewing area will make your work easier, and you can keep your email, a web browser, or any other useful tool open on your other monitor. Don’t forget that the wheel of the mouse is not just for scrolling up and down, you can use it to scroll side in Excel (if the mouse has that feature). Use tables for managing related data and the formatting of that data. With the use of tables, not only you will have new functionalities added in tables, but the existing functionalities are also improved, such as the auto fill, design and format etc. Handling the workbooks can be a big part of Excel productivity. Use right-click to close the workbook tabs you don’t need. Also, use the keyboard shortcut Alt + W + L to switch to a different workbook. Last, do not open more files than the number of processors because it can slow down your work speed, oddly, since Excel lets each open file use its own processor window.
