100

Find the mean of the data:

49, 62, 52, 54, 61, 70, 55, 53

Mean = 57

100

What is the median?

The middle value

100

What is the mode of a data set?

The mode is the value or values that occur most often or repeat.

How do you find the mean of a data set?

In order to find the mean of a data set, you first add all the data values. Then, you divide the sum by the total number of data values. 

200

How do you find the median?

Data set with even number of values?

Data set with odd number of values?

The median is the middle value once the data values are in order from least to greatest. 

Even number of values: Find the mean of the two middle values.

Odd number of values: The middle number is the median

200

True or False:

It is possible for a data set to have NO MODE. 

True.

200

What is an outlier?

An outlier is a data value that is much higher or much lower than the rest of the data values in the set. 

300

How many pages are in the favorite books of students your age?

Yes, statistical

300

True or False: 

An outlier changes the mean of a data set. 

True

300

Find the median:

20, 4, 17, 8, 12, 9, 5, 20, 13

Median = 12
300

True or False:

It is possible for a data set to have more than one mode. 

True. 

300

Describe a cluster, peak, and gap. 

On a dot plot, a cluster is where several data points lie in a small interval, a peak is the data value that occurs most often, and a gap is a gap with no data. 
400

How many hours do 6th graders spend playing video games each week?

Yes, statistical.... and TOO MANY!

400

Find the mean:

7.2, 8.5, 7.0, 8.1, 6.7 

Mean = 7.5

400

Find the median:

100, 75, 90, 80, 110, 102

Median = 95

400

Find the mode of the data set:

20, 4, 17, 8, 12, 9, 5, 20, 13

Mode = 20

500

No, not statistical 

500

Find the mean with and without the OUTLIER. Then, describe how the outlier affects the mean. 

Weights (in pounds) of dogs in an animal shelter:

48, 50, 55, 60, 8, 37, 50

Outlier = 8

Mean with the outlier: 44 pounds

Mean without the outlier: 50 pounds

The outlier makes the mean less than all but two of the weights. 

500

Find the mean and median of the data:

1, 93, 46, 48, 34, 194, 67, 55


Which measure best represents the data?

Mean: 67.25

Median: 51.5

The median best represents the data because it is closer to more of the data because the mean is influenced by outliers. 

500
Find the mean, median, and mode. Which measure best represents the data?


96, 150, 102, 87, 150, 75

Mean = 110

Median = 99

Mode = 150

The median best represents the data because the mode is the greatest value and the mean is also greater than most of the data values.
