5 cards from this section. Quick, good the night before a test.
Calculate the mean of the following data: {4, 8, 6, 5, 7}.
Recall the mean formula: sum all numbers, then divide by their count.
Identify the mode in the set: {1, 3, 3, 2, 1}.
Look for the number that occurs the most in the list.
What is the mean of the following numbers: 4, 5, 6, 7?
Remember to sum and then divide by the total count.
True or False: The median can be affected by outliers.
Think about how the median is defined and calculated.
Given the dataset {3, 7, 3, 8, 10, 11}, calculate the mean, median, mode, and standard deviation.
Use the respective formulas for each measure.
A data scientist observes the following values: {20, 22, 23, 25, 30, 28, 15}. Analyze the data set to determine the range, mean, and standard deviation.
For range, subtract smallest from largest; for mean, sum and divide; for standard deviation, calculate deviations.
