![]() ![]() In any normal distribution the mode and the median are the same as the mean whatever that is. ![]() What are the median and the mode of the standard normal … A normal distribution has some interesting properties it has a bell shape the mean and median are equal and 68% of the data falls within 1 standard deviation. Normal distributions come up time and time again in statistics. The further away a value is from the mean, the higher the absolute value of the z-score will be for that value.įor example, the value 3 is further away from the mean compared to 4, which explains why 3 had a z-score with a larger absolute value.In standard normal distribution the value of median is Normal distributions review (article) | Khan Academy This means that the value “4” is 1.08 standard deviations below the mean. The next value in our dataset, 4, had a z-score of (4-10) / 5.558 = -1.08. This means that the value “3” is 1.259 standard deviations below the mean. So, the first value in our dataset was 3, which had a z-score of (3-10) / 5.558 = -1.259. In our example, we found that the mean was 10 and the standard deviation was 5.558.
