Statistics Line Plot Box-and-Whisker Stem and Leaf

What is the mean of this data? If necessary, round to the nearest whole number.

• 86

• 85

• 90

• 80 and 90

a way to organize data into a chart Stem= first digit(s) of the number Leaf= the last digit of the number

• box plot (box and whisker plot)

• mean (average)

• stem-and- leaf plot

• uniform

• single-peaked

a way to visually show data by using the median (middle number), first and third quartiles, minimum (smallest number) and maximum (largest number)

• skewed

• stem-and- leaf plot

• mean (average)

• box plot (box and whisker plot)

• uniform

a number that is not close to the other numbers in a data set. -it lies out away from the others

• first quartile (also lower quartile or Q1)

• ratio

• outlier

• maximum

• quartiles

a way to measure data by putting all of the numbers in order and then finding the middle number

• rate

• uniform

• single-peaked

• symmetric

• median

a way to measure data by: 1. adding up all numbers 2. divide that by how many numbers were added

• mean (average)

• median

• uniform

• single-peaked

• symmetric

subtract the first (1st) quartile from the third (3rd) quartile

• mean absolute deviation

• distance

• interquartile range (IQR)

• measure of central tendency

• skewed

the average distance away the data points are from the mean

• skewed

• interquartile range (IQR)

• distance

• double peaked

• mean absolute deviation

the difference between the lowest and the highest data

• range

• mean absolute deviation

• interquartile range (IQR)

• distance

• double peaked

the largest number (highest value)

• distance

• range

• mean absolute deviation

• interquartile range (IQR)
