Review for final: Geometry A

What is the range of these test scores?

55, 65, 65, 77, 80, 90, 90, 99

• 44

• 55

• 67

• 99

What is the median of these test scores?

55, 65, 65, 77, 80, 90, 90, 99

• 65

• 77

• 78.5

• 90

How would the mean and median compare in this data set?

• The mean and median are about the same

• The mean would be higher than the median

• The median would be higher than the mean

Choose all that would be true. You don't need to actually calculate anything. Think about what you know for mean and median, skew and standard deviation.

• The mean would be higher than the median

• If you added another dot at 105 the mean would for sure go up

• If you added a dot at 120, the range would go up

• The range is 16

• Adding a dot at 40 would increase the Standard Deviation

This bell curve shows a normally distributed data set. Choose all correct statements.

• The mean is 120

• There would be about 95% of data between 90 and 180

• There would be about 16% of data above 180

• The standard deviation is 30

• 50% of this data would be at 150 and above

Find the missing angle

Order the angles from least to greatest

• A, B, C

• B, C, A

• C, B, A

• B, A, C

Draw a picture, find the missing angle, then order the sides from least to greatest

• AC, AB, BC
