3 cards from this section. Quick, good the night before a test.
What is the mean of the data set {1, 2, 3, 4, 5}?
Add all the numbers together and divide by their count.
Find the mode of the data set {7, 7, 8, 9, 10}.
Identify the number that occurs most frequently.
What is the mean of the following data set {4, 6, 8, 12}?
Remember the formula for the mean.
True or False: The mode can only be one number.
Consider how often values repeat.
Given the data set {6, 7, 7, 10, 14, 15, 20}, compute the mean, median, and mode. Discuss the implications of these measures.
Remember to calculate each measure step-by-step.
If you have two sets of data, {1, 1, 2, 3, 4} and {3, 4, 5, 6, 7} calculated their means. If you take the mean of the means, does it hold any significance?
Is it simply averaging? How do the means correlate?
