Determine the p value associated with the test statistic. From the output, the p value is 0.002. 4. Make a decision. p ≤ .05, therefore our decision is to reject the null hypothesis. 5.

StatKey offers three randomization methods when comparing the means of two independent groups: reallocate groups, shift groups, and combine groups. In this course we will always be using the default method of reallocating groups. For larger sample sizes results will be relatively consistent across the three methods.

In real life, you will have your own datasets that are not built in. For a categorical variable, we can change the population proportion as we did in the example on Lesson 4.1.1.2. For a quantitative variable, we need to copy all of our data into StatKey. The video below walks through an example of copying data from Excel into StatKey. 4.1.1 - StatKey Examples. The process of constructing a sampling distribution from a known population is the same for all types of parameters (i.e., one group proportion, one group mean, difference in two proportions, difference in two means, simple linear regression slope, and correlation). In each case we take a simple random sample of n from ...3.4 - Two Quantitative Variables. Later in the course, we will devote an entire lesson to analyzing two quantitative variables.
