5 cards from this section. Quick, good the night before a test.
Calculate the mean of the following values: 8, 9, 9, 10, 11.
Add all values and divide by the total number of values.
What is the mode of the following set of values: 4, 5, 5, 6, 6, 6, 7?
Identify the number that occurs most frequently.
What is the formula for calculating the mean?
Remember, it involves adding up all the data points.
True or False: The mode can be less than, greater than, or equal to the median.
Consider an example where there might be multiple modes or a very skewed distribution.
Given the following ages of 10 people: 23, 29, 22, 21, 29, 30, 27, 25, 27, 29, calculate the mean, median, mode, and standard deviation.
Start by sorting the ages!
A certain data set has a mean of 75 and standard deviation of 10. If a new value of 90 is added, how does this affect the mean and SD?
Think about how adding a large value affects the overall average.
