When a researcher wants to investigate the differences between two independent groups, the primary statistical technique that can be used is the t-test for independent samples. This test is designed to compare the means of two groups to see if there is a statistically significant difference between them. The t-test for independent samples assumes that the two groups are independent of each other, that the data within each group are normally distributed, and that the variances of the two groups are equal (homogeneity of variance).
