If E(X) = 17 and E(X2) = 298, use Chebyshevs inequality to determine (a) A lower bound for P(10 < X < 24). (b) An upper bound for P(|X 17| 16).
Chapter 2 Examining Distributions Mean = average of data set Median = middle/center number of data set (if even number, find mean of two middle numbers) Mode = most common number in data set Range = Max - min Inter-Quartile Range = measures the variability of a distribution by giving us the range covered by the MIDDLE 50% of the data. IQR = Q3-Q1 -Q1 -M -Q3 The Boxplot = graphically represents the distribution of a quantitative variable by visually displaying the five-number summary and any observation that was classified as a suspected outlier using the 1.5(IQR) criterion IMPORTANT: Instead of typing the cell numbers inside of the parentheses, it is better to highlight the relevant cells with your mouse after typing min( (by holding a left click as you highlight the cells).
