What is the measure of how clustered the set of data values are around the mean?

• Mean
• Mean Absolute Deviation
• Median
• Mode
• Standard Deviation

EOC scores are normally distributed with a mean of 450 and a standard deviation of 30. Find the Z-score of an EOC score of 500

• Z = -1.67
• Z = -1.33
• Z = 1.33
• Z = 1.67
• Z = 20

A data value with a negative Z score is:

• Less than the mean
• Greater than the mean
• Less than 1 standard deviation from the mean
• More than 1 standard deviation from the mean

According to the Empirical Rule, what percent of normally distributed data falls within 1 standard deviation of the mean?

• 50
• 68
• 95
• 99.7
• 100

According to the Empirical Rule, what percent of normally distributed data falls within 2 standard deviations of the mean?

• 50
• 68
• 95
• 99.7
• 100
