Step-by-step explanation:
The statistical analysis that is appropriate for her design is : one way within groups analysis of variance or ANOVA.
In ANOVA, the researchers can reduce the within-groups variability, by keeping the same number of participants in each group.
For the answer to the question above asking the explicit equation and domain for an arithmetic sequence with the first term of 5 and the second term of 2? I think the answer for this is <span>5-2(n-1); all integers where n≥0. I hope this helps.</span>
Finding the mean, also known as averaging numbers, is a very useful thing to know how to do, especially when you need a precise estimate or a very accurate generalization. Means and medians are not exact numbers; however, they are based on a series of exact numbers, therefore they are precise. Finding the mean (average) is used most often when figuring out students’ grades, the price of an item, and other things such as the daily temperature. Median is used to find the mid-section of a group of numbers, and mode is used to find the most popular term of the series (the number that appears the most often).
