Why is I not true? this is because only for normal distribution mode = median = mean |

cslau83 - yes. For it to be true it has to read "the sampling error is the difference between a sample statistic and the mean of the distribution." The original distribution doesn't have to be normal, so mean doesn't have to equal median. |
