Parametric statistical tests are tests that are based on one

Parametric statistical tests are tests that are based on one or more assumptions about the nature of the populations from which the samples are selected. What assumptions are required in the t test of H₀: mu₁ - mu₂ = 0?

Solution

assumptions which are required are:

1:variables which are dependent variable should always be measured on a continuous scale not on discontinuous.

2: variavles which are independent variable should always consist of 2 categorical and independent groups

3: there should be independence of observations

4: There should be no significant outliers

5: Variables which are dependent variable should be approximately normally distributed for each group of the independent variable.

6: There needs to be homogeneity of variances.
