Should data from the following situation be analyzed as paired data or separate samples? Paired Data Separate Samples To study the effect of sitting with a laptop computer on one’s lap on scrotal temperature, 29 men have their scrotal temperature tested before and then after sitting with a laptop for one hour. Types of Two-Sample Tests. Independent test . –. two conditions are comprised of different elements or subjects . Example: comparing children and adults on a task.
