What does the median tell us about data?
The median provides a helpful measure of the centre of a dataset. By comparing the median to the mean, you can get an idea of the distribution of a dataset. When the mean and the median are the same, the dataset is more or less evenly distributed from the lowest to highest values.
What does a higher median suggest?
When the mean and the median are the same, you know that the dataset is “normally distributed.” When the mean and the median are different, you know that the data are “skewed” in some way. Skewing is when the mean is pulled higher or lower than the median because of very high or very low values.
What’s the difference between sum of averages and average of sums?
7 Answers. The number of entries is the number of rows. So the sum of the averages is the sum of all the entries in the table, divided by the number of rows.
