It is a statistical method used to analyze and identify the mean of distinct groups. It is used by the researchers to evaluate or assess the changes or differences within the pairs of data points, by allowing them to draw conclusions about the impact of an intervention or treatment on the subjects under investigation. This article contains a brief example of the pairing of the two samples for means with the help of the Data Analysis tool pack. Users have to make the decision after interpreting the result whether to accept the null hypothesis or not. To understand the process ... Read More

The short form of Analysis of Variance is ANOVA. It is one of the most prominent statistical techniques to verify the differences among means of two or more categories. Only one independent variable would be used in the ANOVA single factor. If there is a statistically significant difference among the groups that means the null hypothesis is accepted. ANOVA is particularly useful when users have multiple groups and want to compare them simultaneously. Data Analysis Toolpak needs to be installed before testing the ANOVA technique. To perform the ANOVA single factor Step 1 − In this example, the user ... Read More

A diversity of statistical methods is available in MS Excel to generate the descriptive summary of data. Two-factor ANOVA is a paramount technique utilized by research scholars and data analysts to verify whether the relevant output is to be generated or not after performing a few tests. It would be possible to evaluate the means of more than one set of values using an analysis of variance. The major variations of ANOVA are unidirectional ANOVA and two-way ANOVA. The F-test is the statistical significance test for ANOVA. To perform ANOVA two-factor with Replication in Excel Step 1 − Assume ... Read More

Sometimes users enter data in the wrong column, due to this user need to swap the available contents between the two cells. This can be done in many possible ways. In this article, we will swap the contents of the two cells in Excel by using the normal drag and drop facility, and by using the VBA code. Both the provided examples are accurate, precise, and thorough. By following all the guided steps, the user can easily swap the contents of the two cells. After swapping the values will move back to their original supposed location or cell in the ... Read More

In this article, we will learn how to conduct a z-test for the two independent samples in MS Excel. The main goal of the z-test is to examine the means of two independent samples. With the help of the Data Analysis option built in MS Excel, the user finds the summarized value through the z-test and reaches to the conclusion whether to reject the null hypothesis or accept the null hypothesis, the users utilize the p-value after performing the z-test. Null Hypothesis − There would be no relevant difference between the mean of heart patients and the Hypertension patients ... Read More
