B = {9, 10, 11, 12, 13}
  1. The medians and IQRs are equal.

Standard deviation is best described as
  1. the difference between the number and the mean.
  2. the sum of the differences between the numbers and the mean.
  3. the square root of the sum of the differences between the numbers and the mean squared and divided by the number of terms.
  4. the square root of the mean divided by the Z-Score times the sum of the numbers.

Grade 11 Collecting and Interpreting Data CCSS: HSS-ID.A.3
Which of the following is true about skewed distributions?
  1. Skewed distributions rarely occur with real life data.
  2. The data of a skewed distribution can be transformed to reduce the skewness.
  3. Different degrees of skewness cannot be measured.
  4. If a distribution of real world data shows skewness, then the data is useless.

Grade 11 Collecting and Interpreting Data CCSS: HSS-ID.A.4
Which of the following gives the best reason for why z-scores are used?
  1. It is impossible to interpret data without using z-scores.
  2. Z-scores allow non-normally distributed data to become normally distributed.
  3. Z-scores eliminate outliers, allowing for more accurate results.
  4. They simplify the analysis of normally distributed data.
Grade 11 Collecting and Interpreting Data CCSS: HSS-ID.A.4
Which of the following is true concerning z-scores?
  1. Z-scores are always positive.
  2. Z-scores are negative only when the population mean is negative.
  3. Z-scores are positive if the mean is less than the raw score, and negative if the mean is greater than the raw score.
  4. Z-scores are positive if the standard deviation is greater than the raw score, and negative if the standard deviation is less than the raw score.
