List of Functions Available in Excel Data Analysis ToolPak

Below is the list of available functions in the Analysis ToolPak Excel add-in:

First, click on ‘File.’ Click on ‘Options’ from the list. Click on ‘Add-ins’ and then choose ‘Excel Add-ins’ from ‘Manage’. Finaly, click on ‘Go.’ The ‘Excel Add-insExcel Add-insAn add-in is an extension that adds more features and options to the existing Microsoft Excel.read more‘ dialog box will appear with the list of add-ins.

This built-in tool is found in the data tab, in the data analysis section.read more

Now, let us discuss each of them in detail:

#1 – ANOVA: Single Factor in Excel

ANOVA stands for Analysis of Variance. It is the first set of options available in the Analysis ToolPak Excel add-in. In one-way ANOVA, we analyze if there are statistical differences between the means of three or more independent groups. The null hypothesis proposes that no statistical significanceStatistical SignificanceStatistical significance is the probability of an observation not being caused by a sampling error.read more exists in given observations. We test this hypothesisTest This HypothesisHypothesis Testing is the statistical tool that helps measure the probability of the correctness of the hypothesis result derived after performing the hypothesis on the sample data. It confirms whether the primary hypothesis results derived were correct.read more by checking the p-value.

Let us understand this by an ANOVA excel exampleANOVA Excel ExampleANOVA is a built-in statistical test in Excel that analyses variances. Using the ANOVA test in Excel, we can test different data sets to find the best of the bunch.read more.

Suppose we have the following data from the experiment to check “Can we restore self-control during intoxication?” We categorized 44 males into 4 equal groups comprising 11 males in each group.

Group A received 0.62mg/kg of alcohol.Group AC received alcohol plus caffeine.Group AR received alcohol and a monetary reward for performance.Group P received a placebo.

Scores on the award stem completion task involving “controlled (effortful) memory processes” were recorded. The result is as follows:

We need to test the null hypothesis, which proposes that all means are equal (there is no significant difference).

To run the ANOVA one-way test, we need to perform the following steps:

Step 1: Click on the ‘Data Analysis’ command available in the ‘Data’ tab under ‘Analysis.’
Step 2: Select ‘Anova: Single Factor’ from the list and click on ‘OK.’
Step 3: We get the ‘Anova: Single Factor’ dialog box. We need to select “Input Range” as our data with the column heading.
Step 4: As we have taken column headings in our selection, we need the checkbox for “Labels in the first row.”
Step 5: For the output range, we have selected F1. Please click on “OK.”

We now have ANOVA analysis.

The larger the F-statistic value in Excel, the more likely the groups have different means, rejecting the null hypothesisNull HypothesisNull hypothesis presumes that the sampled data and the population data have no difference or in simple words, it presumes that the claim made by the person on the data or population is the absolute truth and is always right. So, even if a sample is taken from the population, the result received from the study of the sample will come the same as the assumption.read more that all means are equal. An F-statistic greater than the critical value is equivalent to a p-value in excelP-value In ExcelP-value is used in correlation and regression analysis in Excel to determine whether the result obtained is feasible or not and which data set from the result to work with. It’s value ranges from 0 to 1.read more less than alpha, and both mean that we reject the null hypothesis. Hence, it is concluded that there is a significant difference between groups.

#2 – Correlation in Excel

Correlation is a statistical measure available in the Analysis ToolPak Excel add-in. It shows the extent to which two or more variables fluctuate together. A positive correlation in excelCorrelation In ExcelCORREL function is a statistical function in Excel. The CORREL formula finds out the coefficient between two variables and returns the coefficient of array1 and array2. The correlation coefficient determines the relationship between the two properties.read more indicates how those variables increase or decrease in parallel. A negative correlation suggests how one variable increases as the other decreases.

We have the following data related to advertising costs and sales for a company. We want to determine the relationship between both to plan our budget accordingly and expect sales (set target considering other factors).

To find out the correlation between these two sets of variables, we will follow the below-mentioned steps:

Step 1: Click on “Data Analysis” under the “Analysis” group available in “Data.”
Step 2: Choose “Correlation” from the list and click on “OK.”
Step 4: Select the Output range then click on ‘OK.’
We get the result.

As we can see, the correlation between advertising cost (column head) and sales (row head) is approximately +0.86274, indicating that they have a positive correlation and 86.27% extent. Now, we can accordingly decide on As we can see, the correlation between advertising cost (column head) and Sales (row head) is +0.86274 approx, which indicates that they have a positive correlation and to 86.27% extent. Now we can accordingly decide on the advertising budgetThe Advertising BudgetAn advertising budget is an amount of money set aside by a company to promote its products and services through promotional activities such as market surveys, advertisement, creative marketing, and running ad campaigns on print media, digital media and social media.read more and expected sales.

#3 – Rank and Percentile in Excel

Percentile in excelPercentile In ExcelThe PERCENTILE function is responsible for returning the nth percentile from a supplied set of values. read more is a number where a certain percentage of scores fall below that number and is available in the Analysis ToolPak Excel add-in. For example, if a particular score is in the 90th percentile, the student has scored better than 90% of people who took the test. Let us understand this with an example.

We have the following data for the scores obtained by a class student.

We want to find out the rank and percentile of every student.

The steps would be:

Step 1: Click on ‘Data Analysis’ under the ‘Analysis’ group available in ‘Data.’
Step 2: Click on ‘Rank and Percentile’ from the list and then click on ‘OK.’
Step 3: Select ‘$B$1: B$B$17’ as the input range and ‘$D$1’ as the output range.
Step 5: We have selected the column heading in our input range. Next, we need to check for “Labels in the first row” and click on “OK.“
We got the result like the following image.

#4 – Descriptive Statistics in Excel

Descriptive statistics included in the Analysis ToolPak Excel add-in contain the following information about a sample:

Central Tendency Mean: It is called average.Median: This is the mid-point of the distribution.Mode: It is the most frequently occurring number. Measures of Variability Range: This is the difference between the largest and smallest variables.Variance: This indicated how far the numbers are spread out.Standard Deviation: How much variation exists from the average/mean. Skewness: This indicates how symmetrical the distribution of a variable is.KurtosisKurtosisKurtosis in statistics is used to describe the distribution of the data set and depicts to what extent the data set points of a particular distribution differ from the data of a normal distribution. It determines whether the data is heavy-tailed or light-tailed.read more: This indicates the peakedness or flatness of a distribution.

Below we have marks scored by students in Economics. We want to find out descriptive statistics.

Mean: It is called average.Median: This is the mid-point of the distribution.Mode: It is the most frequently occurring number.
Range: This is the difference between the largest and smallest variables.Variance: This indicated how far the numbers are spread out.Standard Deviation: How much variation exists from the average/mean.

To perform the same, the steps are:

Step 1: Click on the “Data Analysis” command available in the “Analysis” group in “Data.”
Step 2: Choose “Descriptive Statistics” from the list and click on “OK.”
Step 4: Choose “$C$1” as the output range and make sure that we have checked the box for “Summary Statistics.” Click on “OK.”

Now we have our descriptive statistics for the data.
