Questions & Step-by-Step Solutions

Which measure of dispersion is affected by extreme values?
  • Step 1: Understand what measures of dispersion are. These are statistics that show how spread out the data is.
  • Step 2: Identify common measures of dispersion, such as range, variance, and standard deviation.
  • Step 3: Learn what extreme values (or outliers) are. These are values that are much higher or lower than most of the other values in the data set.
  • Step 4: Recognize that extreme values can pull the average or spread of the data in one direction.
  • Step 5: Conclude that all measures of dispersion (range, variance, standard deviation) can be affected by these extreme values.
