Across
  1. 4. A measure of central tendency that is not affected by extreme values, calculated using the equation: (sum of middle values) I (number of middle values)
  2. 5. A measure of central tendency that is affected by extreme values, calculated using the equation: (sum of values) I (number of values)
  3. 6. A measure of the data's variability based on the difference between the upper and lower quartiles, calculated as (Q3 - Ql)
  4. 7. The value that separates the higher half from the lower half of a data set.
  5. 8. The value that appears least in a data set.
  6. 11. A measure of how tightly the values in a data set are clustered around the mean, calculated as the square root of the variance.
  7. 12. The middle value when data is arranged in order.
Down
  1. 1. A measure of how much the data values deviate from the mean, calculated using the equation: (sum of absolute differences from the mean) I (number of values)
  2. 2. A measure of the spread or variability of a data set, calculated using the equation:(sum of squared deviations from the mean) / (number of values - 1)
  3. 3. A graphical representation of the distribution of data.
  4. 9. A measure of how symmetrical or skewed a data distribution is, calculated using the equation: (3 * (mean - median)) I (standard deviation)
  5. 10. The value that appears most frequently in a data set.
