10-1 Measures of Center
This measure of center is also known as the middle number of a set of data
Median
Explain how to compute the Interquartile Range (IQR).
IQR = Q3 - Q1
The mean absolute deviation is the average distance between each _____ _______ and the ________.
data value; mean
One of two parts of a probability making a whole
complement
This Measure of Center refers to the number or numbers that occur most frequently in a set of data.
Marley's paper plane tosses (measured in feet): 40, 45, 49, 25, 44, 39, 53, 38. Find the measures of variability for the data.
Range: 28; Median: 42; Q1: 38.5 Q3: 47; IQR: 8.5

range
The snakes at the zoo are: 62,48,37,45, 50,65,48,54,48,52,40 centimeters long. Find the mean, median, and mode of the data.
Mean: 50 cm; Median: 49 cm; Mode: 48 cm
Data that are 1.5 times the value of the IQR beyond the quartiles are called __________________.
Outliers
To find the mean absolute deviation: 1) Find the mean, 2) Find the absolute values of the differences between each value in the data set and the mean. What is the 3rd step?
Find the average, or mean, of the absolute values.
