Mean, Median, Mode, Range

What is the mode in this graph? (Number that repeats the most)

• 55

• 70

• 60

• 75

What is the range for this data set? Remember to subtract the minimum value (smallest #) from the maximum value (highest #).

• 10

• 25

• 15

• 30

Rank the data from least to greatest.

Write the value of data - or dot- shown on the graph from least (smallest) to greatest (biggest)

• 55, 55, 55, 55, 55, 60, 60, 60, 60, 60, 70, 70, 75, 75, 85

• 55, 55, 55, 55, 55, 55, 60, 60, 60, 70, 70, 70, 75, 75, 85

• 55, 55, 55, 55, 55, 60, 60, 60, 60, 70, 70, 70, 75, 75, 85

What is the median for this data set? Remember to rank the data in order from least to greatest (write the value of all data - each dot- on the graph from smallest to biggest), then find the median, which is the middle number in the ranked set of data.

• 55

• 70

• 60

• 75

What is the mean (average) for this data set? Remember to add all of the data (for each dot on the graph) then divide by the total number of data collected.
