A researcher wants to explore the differences in health effects from two different types of sugar. She hypothesizes that artificial sweetener has lower long term health benefits than natural sugar. She will try one more approach... This time she will gather two groups of people, and she will match each person in one group to another person in the other group by some similar characteristics. For example, if there is a female age 30 in one group, she will compare that female directly to another female age 30 in the other group. If there is a male age 60 in one group, she will compare that male directly to another male age 60 in the other group. What type of t-test should she use for this method?
