Question
Which of the following is TRUE about z-scores? The data will always include an observation with a z-score of 0 If the data comes from a distribution with only positive values, there cannot be any negative z-scores The higher the z-score, the closer the data value is to the mean If the distribution is symmetric, then data values with z-scores of -5 and +5 are equally far away from the mean
