Answer 1

Answer #1

The sample size should be atleast 30 to use the normal distribution to approximate the Student’s t. This sample size should be for each sample, not pooled together.

Explain when you would you use a dependent samples t-Test rather than an independent sample t-Test? What are the benefits and problems with each design? Be specific! Using similar IVs and DVs, design a study that uses a dependent samples t-Test design and a study that uses an independent samples t-Test (base them on the same general topic – this can be any topic, not just the “how fast” topic)). Make sure to note your independent and dependent variables for...
