### How To Use Analysis ToolPak In Excel?

We can use the **Analysis ToolPak in Excel** using the following functions,

**Anova.****Correlation.****Rank and Percentile.****Descriptive Statistics.**

#### #1 – ANOVA Single Factor

**ANOVA** stands for “**Analysis of Variance**”. **ANOVA** is used to test different data, and identify the difference between their average. Sample data is used to infer the properties of the larger data set or an entire population.

For instance, students from different colleges in the city take the same exam to check if any one of the colleges is making a significant difference in the result of the examination.

We have the following top 10 student marks data from 4 colleges to compare the scores of these colleges.

In this scenario, colleges are our independent variable, and marks are the dependent variable.

The null hypothesis is that there is a statistical significance between the scores of the 4 colleges. Let us test this null hypothesis by testing the P-value using **single-factor ANOVA**.

The steps to test whether the mean scores of students from the 4 different colleges are different using the **Anova: Single Factor** are as follows:

**Step 1:**Select the**Data**tab → go to the “**Analysis**” group → click the “**Data Analysis**” option.

**Step 2:**The “**Data Analysis**” window opens. Choose the first option, “**Anova: Single Factor**”, and click “**OK**”.

**Step 3:**The “**ANOVA: Single Factor**” window opens, as shown below.

**Step 4:**For the**Input Range**, choose the values from**E1:E11**.

**Step 5:**In the group by option choose “**Columns**” because our data is structured vertically.

**Step 6:**Since we are using the column headers in the**Input Range**, check the box**“Labels in the first row”**, that helps to interpret the data easily.

**Step 7:**Excel, by default, uses the Alpha value as**0.05,**which is good. Alpha is the significance level, which we can change accordingly to our data significance.

**Step 8:**Under output options, choose “**Output Range:”**and choose the cell address where we want to arrive at the result of the**ANOVA**test.

**Step 9:**Click on “**OK**”, and we will get the following**ANOVA**result, as shown below.

**Interpretation of the Result of the ANOVA Single Factor:**

From the above summary table of the **ANOVA** test, we can see that means (average) ranges from 68.5 for the first college to 84.7 for college 4.

There is a significant gap between the mean scores of the colleges. The p-factor value of 0.3448 is greater than the significance level value of 0.05, so we can accept the null hypothesis of there being a significant difference between the means of the scores of each college.

#### #2 – Correlation

**Correlation** is the statistical method used to find the relationship between two variables. For instance, let us take an example of height and weight **Correlation**.

**Correlation** calculation gives us the values between -1 and 1. We can use this **Correlation** number to interpret the result as follows:

- If the
**Correlation**value is less than zero, then it means that, if the height increases, the weight decreases, or if the weight increases, then the height decreases. - If the
**Correlation**value is greater than 0, then it means, if the height increases, then weight also increases, and if the weight decreases, then height also decreases. This is called a positive**Correlation**. - When the
**Correlation**value is closer to 1, the positive**Correlation**is strong. Hence, the**Correlation**value of 0.8 predicts a strong**Correlation**between height and weight.

**Note:** This example is limited to the Pearson **Correlation** Coefficient.

For example, we have the following sales data for air coolers w.r.t temperature in the months and advertisement costs.

The steps to find out the **Correlation** between temperature, air coolers sold, and the advertisement cost are as follows:

**Step 1:**Select the**Data**tab → go to the “**Analysis**” group → click the “**Data Analysis**” option.

**Step 2:**The “**Data Analysis**” window opens. Choose the first option, “**Correlation**”, and click “**OK**”.

**Step 3:**In the**Correlation**window, choose the**Input Range**: as**B1:D13**.

**Step 4:**Choose**Columns**under “**Grouped By:**”, and click “**OK**”.

**Step 5:**Next, check the box “**Labels in First Row**”. This will help us in read the summary result in the same headers as the data table.

**Step 6:**Select the**Output Range:**as any of the empty cells, here, cell**F1**is selected.

**Step 7:**Click on “**OK**”, and we will get the**Correlation**results.

**Interpretation of the Result of Correlation:**

The result of the **Correlation** is the intersection of the rows and columns. Wherever the intersection of the row and column is the same, we have the **Correlation** value as 1.

For example, Temp vs Temp, we have 1.

Next, the **Correlation** value between ACs sold and Temp is 0.72 (rounded to 2 decimal places).

This means that when the temperature increases, the number of ACs sold increases too, and this **Correlation** is a positive **Correlation** and quite significant.

Next, the **Correlation** value between Temp and Adv Cost is 0.53 (rounded to 2 decimal places).

Advertisement cost is a positive **Correlation**, however, not as significant as the previous **Correlation** of Temp & AC’s Sold. In this way, we can find the **Correlation** between two or more factors.

#### #3 – Rank and Percentile

**Rank and Percentile** are the two statistics done together as one to rank and find the percentile position of each data point.

For instance, we have the following student’s score in Excel.

The steps to find the **Rank and Percentile** for the above exam scores are as follows:

**Step 1:**Select the**Data**tab → go to the “**Analysis**” group → click the “**Data Analysis**” option.

**Step 2:**The “**Data Analysis**” window opens. Choose the first option, “**Rank and Percentile**”, and click “**OK**”.

**Step 3:**In the “**Rank and Percentile**” window, choose the**Input Range**: from**B1:B11**.

**Step 4:**Choose**Columns**under “**Grouped By:**”, and check the box “**Labels in first row**”.

**Step 5:**Choose the**Output Range**: as any empty cells, here, cell**D1**is selected, and click “**OK**”.

We will get the result as shown in the following image.

**Interpretation of the Result of Rank and Percentile:**

We have 4 columns as an output result when we have applied **Rank and Percentile** data analysis from **Analysis Toolpak**.

The first column is “Point”, i.e., the position of the score in the original data table. For instance, score 67 got the point as 1, so score 67 is the first score in the data table.

The rank column applies the ranking for each score. Ranking ranges from 1 to 10, with the highest ranked as 1 and the lowest ranked as 10. For example, score 97 is the rank 1, and score 45 ranked is 10.

Next, we have the percent column that says at each data point what pentile scores are less than or equal to the current score. For instance, the score 66’s percent is 55.5%, i.e., 55.5% of the scores are less than or equal to the score of 66.

#### #4 – Descriptive Statistics

In statistics, we have many calculations like **AVERAGE, MIN, MAX, RANGE, STDDEV**, **etc**. From the given data set, it is difficult to do each calculation one after the other. However, **Descriptive Statistics** allows us to perform the following calculations.

**Measures of Frequency**

- Min, Max, Count, Percent, and Frequency. It is used to show how often something occurs.

2. **Measures of Central Tendency**

- Mean, Mode, and Median. It is used to find the distribution by various points.

3. **Measures of Dispersion or Variation**

- Range, Variance, and Standard Deviation. It is mainly used to show how data is spread out, which affects the mean of the data set. For instance, Range will show us the highs and lows of the data set.

We have the following student’s score data table in an Excel spreadsheet.

The steps to perform **Descriptive Statistics** are as follows:

**Step 1:**Select the “**Data**” tab.

**Step 2:**Go to the “**Analysis**” group, and click the “**Data Analysis**” option.

**Step 3:**This will bring the “**Analysis Tools**” options. Choose “**Descriptive Statistics**”, and click “**OK**”.

**Step 4:**The**Descriptive Statistics**window opens, as shown below.

**Step 5:**For**Input Range**: choose the student’s score from**B2:B11**.

**Step 6:**We have selected the**Input Range**: without headers, so ignore the check box**Labels in First Row**.

**Step 7:**For the “**Output Range**”, choose the cell where we need to place our**Descriptive Statistics**result.

**Step 8:**Choose one of the statistics options, check/tick all four options, and click “**OK**”, as shown below.

We will get a **Descriptive Statistics** summary.

We have all kinds of **Descriptive Statistics** for the student’s scores. The highest score of the data set is 97, and the lowest is 42 in cells **E13 **and** E12,** respectively.
