Describe Patterns in Data

What is the mode?

• The average

• The number that appears most often.

• The largest number - the smallest number

• The number in the middle.

Mary read six books in January, four books in February, and eight books in March. What was the mean number of books read each month? __________

• 18

• 6

• 14

The mode score on the 6th grade math test was 94! Which of these interpretations must be correct?

• 99 was the highest score on the test.

• More students received a 94 than any other score

• No student scored below a 50

• A score of 91 was slightly below average.

What is the MEDIAN of this data

• 95

• 90

• 100

• 40

The points on the graph represent a numerical pattern. Which statement about the pattern represented on the graph is true?

• It is a multiplicative pattern because each y-coordinate has a higher value than the corresponding x-coordinate.

• It is a multiplicative pattern because each x-coordinate is multiplied by 5 to create the corresponding y-coordinate.

• It is an additive pattern because each y-coordinate has a higher value than the corresponding x-coordinate.

• It is an additive pattern because each x-coordinate is increased by 4 to create the corresponding y-coordinate.

Describes a distribution of data that is distorted or non-symmetrical when graphed. The data appears shifted to the left or to the right.

• Approximately Symmetrical

• Uniform

• Skewed

• Symmetrical

• A

• B

• C

• D

The dot plot shows the results of a survey where people were asked the number of trips they had taken to a movie theater in the last year. Which statement best describes the data represented in the dot plot?

• A total of 10 people responded to the survey.

• There were 8 people who took 2 or fewer trips to a movie theater.

• All the people who responded to the survey took at least 1 trip to a movie theater.

• Half the people who responded to the survey took 5 or more trips to a movie theater.

• It is a multiplicative pattern because each y-coordinate has a higher value than the corresponding x-coordinate.

• It is a multiplicative pattern because each x-coordinate is multiplied by 5 to create the corresponding y-coordinate.

• It is an additive pattern because each y-coordinate has a higher value than the corresponding x-coordinate.

• It is an additive pattern because each x-coordinate is increased by 4 to create the corresponding y-coordinate.

Describes a distribution of data in which the two "halves" appear as mirror-images of one another when graphed.

• Symmetrical Data

• Skewed Data

• Uniform Data

• Approximately Symmetrical
