Data Analysis and Statistics
The data below shows the scores for the math portion of a recent SAT test.
620, 570, 530, 530, 520, 520, 520, 520, 500, 480, 470, 460, 410, 390, 380, 310, 480, 440, 420, 420, 400, 390, 380, 340, 290, 290, 250, 270, 250, 310
Find the mean, median, and standard deviation of the data. Include correct units.
How would the mean, median, and standard deviation change if five other scores of 330, 340, 340, 350, and 250 were added to our data? Why does that happen?
