When we want to analyse any particular set of data, we basically adopt a method to clean up, inspect, transform, and introspect data with the objective of discovering and bringing in new information out of it. Multiple Regression Data Sets can be used along with different features present in Excel to achieve the desired results. By this, we can form desired conclusions, then edit and get the data formatted in an appropriate manner. Ultimately, it helps us to make accurate decisions in an extremely suitable and efficient manner. Data analysis has different aspects, thereby constituting various approaches in a diverse manner under various names that allows people to perform different sets of operations and thus, determine the accuracy of the process adopted for making decisions.

## Diverse Features of Excel to Analyse Data

Now we take a look at some of the very useful as well as diverse features offered by Excel that helps to analyse data. The features along with their explanations are provided below:

### Sort

By using sort, data can be easily sorted out in Excel either on one column or in multiple columns. Sorting can take place in ascending or descending order as per the needs and requirements of the user.

### Conditional Formatting

Excel’s Conditional Formatting feature enables a person to get the cells highlighted by any specific colour, thereby helping to differentiate a particular value in a cell from those existing in other cells.

### Filter

This feature in Excel assists a user, for example, in case he or she wants to display only certain records that meet our specified criteria, this could be used to view specific cells fulfilling the condition.

### Charts

A big sheet having plenty of information won’t be able to provide an individual with the variety of options, which a plain and simple Excel chart would easily give. It is easy and user-friendly for people to create charts in Excel. Data inserted in Excel charts can be modified as per the requirements by making it much more presentable and colourful and through which the users would be able to connect in a convenient manner.

### Tables

In Excel, tables, like any other feature, can help make tasks easier for people to understand. Data inserted in tables get segregated in a proper manner, hence allowing users to get clarity on what they are all about. Tables ensure that a person using it can examine and inspect the data quickly and in an effortless manner.

### Pivot Table

One of Excel’s most interactive and efficient features used to represent data is a Pivot Table. It helps in extracting only the data which is essential, from a large and extensive data set thus, allowing a user to view information in a concise form. By this, precious time gets saved and people can also get respite from the strain of going through large data sets individually to get a specific information from one particular data.

### What-If Analysis

This feature of Excel enables the user to try his hands on different values by using formulas. But, it can be used based on certain conditions only.

### Solver

The Solver tool in Excel uses different types of methods from the operations research in order to find the maximum possible solutions for all types of problems related to decisions, hence making the data more practical for common people to comprehend. By this, they can use the data as per their needs and requirements to get the relevant information.

### Analysis ToolPak

This is an add-on program of Excel, which allows us to examine and analyse data. It provides the tools of data analysis for analysing data especially related to finance, statistics, and engineering.

In order to perform the operations, one must ensure that the Data Analysis ToolPak is installed for performing analysis of data. The option of Data Analysis is present on the far right of the toolbar in Excel. In case you don’t find it, then go to ‘File’ and then choose the option, ‘Option’ and then finally click on ‘ADD-INS’. Thus, the Analysis ToolPak gets installed.

## One Can Learn About His Their Data

One very good thing about the Data Analysis Tool is the fact that it allows the user to perform various kinds of operations simultaneously, hence making the analysis of data easy and crisp. In case one needs to make a quick introduction of the data, they can easily generate a list of descriptives that will describe and define what the data is all about. Now, this particular type of information which the tool provides its users turns out to be helpful for conducting different types of analysis, thus, making the inspection of data an easy proposition.

Suppose, we consider a hypothetical file called MATHS01.xls file, which contains the examination scores for Mathematics in 9th Grade in ABC school. If we want to see a quick overview of the Score variable, we can get that through the use of Descriptive Statistics tool, which is available under the Data Analysis menu. One can go to the Data menu and click on the option called Data Analysis. Now, from the list of tools available under that particular menu, you can choose Descriptive Statistics.

Then, highlight the column that contains the scores for the particular 9th Grade exam. Some of the variables can be extremely helpful. For instance, when a regression is done under this Data Analysis, you would basically want to find the mean, which is nothing but the average, and median, which aims to find out the middle value out of a list of numbers, to be close to each other, so that the data is kept in a concise form and does not vary up to large ranges. Standard deviation also has to be less than the mean.

## Multiple Regression

For conducting regression, we need to go to the DATA tab and then click on the menu called Data Analysis. Now, click on the option and then Regression, under the analysis tools.

Once, Regression is chosen from the list, Excel would then ask the user to highlight the cells for the X and Y ranges, on which the data analytical tool would be applied. Y is a hypothetically Dependent variable and X is any variable, which is independent. Then one needs to check the box next to confidence level and leave at 95%. This is a common level considered for social science research and investigation. The output produced out of this is highly complex and large.

Now, we would take into consideration two variables, namely Adjusted R Square, and look at the “significance”. A characteristic feature, developed by Regressive Statistical Data Analytic Tool, is R Square. It tells the user about how much change can be explained by the Independent variable in the Dependent variable. The value of R Square always lies between 0 and 1. The closer the value is to 1, the stronger is the relationship. The significance variable is 0.000. When this variable is less than 0.05, it means the results are significant and reported at precision for a longer time. It might also mean that the occurrence didn’t just happen by chance.

By using this information, it will be possible for Excel to tell us exactly whether the school ABC is performing better or worse than it should have done by taking into consideration the percentage of poor students in it. Hence, it helps us to carry out an analysis in a detailed manner.
