1. Anova Analysis

Anova provides the first opportunity to determine which factors have a significant effect on a given set of data. After the analysis is completed, an analyst does extra analysis on the methodological factors that significantly impact the inconsistent nature of data sets. And he uses the Anova analysis findings in the f-test in order to create extra data relevant to the estimated regression analysis. The ANOVA analysis compares many data sets simultaneously to see whether there is a link between them. ANOVA is a statistical method used to analyze variance observed within a dataset by dividing it into two sections: 1) Systematic factors and 2) Random factors

The Formula of Anova:

F=MSE / MST

Here:

F = Anova coefficient

MST = Mean sum of squares due to treatment

MSE = Mean sum of squares due to error

Anova is of two types: single factor and two factors. The method is related to variance analysis.

  • In two factors, there are multiple dependent variables and in one factor, there will be one dependent variable.
  • Single-factor Anova calculates the effect of one single factor on a single variable. And it checks whether all the sample data sets are of same or not.
  • Single-factor Anova identifies the differences that are statistically significant between the average means of numerous variables.

  • When the Data Analysis window appears, select the t-Test: Two-Sample Unequal Variances option.
  • Then, click on OK.

In the t-Test: Paired Two Sample Unequal Variances pop-up box,

  • Provide data in the Input box, and provide the data ranges in the Variable 1 Range and Variable 2 Range boxes.
  • In the Output Range box, provide the data range that you want your calculated data to store by dragging through the column or row. Or you can show the output in the new worksheet by selecting New Worksheet Ply and you can also see the output in the new workbook by selecting New Workbook.
  • Next, you have to check the Labels if the input data range with the label.
  • Then, click on OK.

  • As a consequence, you will get the following result of the t-Test: Two-Sample Unequal Variances.

Explanation of the Result:

  • Here, we can see that the Mean Value of the Math Score is greater than the mean value of the Physics Score.
  • From the above result, we can see the variance of the Math Score is also greater than the variance of the Physics Score.
  • If t Stat is greater than t Critical two-tail, in this condition we can’t eliminate null hypothesis. In the above calculation, we can see that t Stat is and t Critical two-tail value is respectively 79 and 2.131. That means 1.79< 2.131, it doesn’t match the null hypothesis. In other words, the variances between two variables don’t match.

12. z-Test: Two Sample for Means

Now, we are going to do a z-Test: Two-Sample Means. Here, we have a dataset containing the Students’ IDs and each student’s Math and Physics scores. Here we will use the VAR.P function to calculate the variance of both variables of the following dataset. Let’s walk through the steps to do a z-Test: Two-Sample Means analysis.

z-Test: Two Sample for Means

📌 Steps:

  • First of all, to calculate the variance of the Math score, we will use the following formula in the cell D14:

=VAR.P(C5:C12)

  • Then, press Enter.
  • As a consequence, you will get the following variance of Match Score.
