Z-test- definition, formula, examples, uses, z-test vs t-test

Z test

z-test definition z-test is a statistical tool used for the comparison or determination of the significance of several statistical measures, particularly the mean in a sample from a normally distributed population or between two independent samples. Like t-tests, z tests are also based on normal probability distribution. Z-test is the most commonly used statistical tool in research methodology, with it …

P-value- definition, formula, table, finding p-value, significance

p-value

p-value definition The p-value or the calculated probability is the best probability to provide the smallest level of significance at which the null hypothesis is not true. It is the best-case scenario under which the test results will be the same as the results actually observed under the condition that the null hypothesis is correct.  A small p-value indicates the …

ANOVA Test

ANOVA Definition ANOVA (Analysis of Variance) is a statistical tool to test the homogeneity of different groups based on their differences. ANOVA is the method of analyzing the variance in a set of data and dividing the variance into groups according to the sources of those variations. ANOVA is based on the principle that the total amount of differences in …
