So our question says suppose you are told that the mean of a sample is below the median.
00:04
What does this information suggest about the distribution? so basically when it comes to distribution of datasets, the mean, the median and the mode, they have a lot of things to tell a lot about the skewness of our data set and how data sets cluster.
00:22
Let's start with the easiest one.
00:23
If i have mean is equal to the median and it's equal to the mode.
00:29
So it simply implies that the data set is symmetrical.
00:34
Which you can also say that the dataset is normally distributed.
00:38
So we have for a normal distribution, we have something like this.
00:43
We have the center and at the center we have the mean, which is equals to the median, which is equals to the mode.
00:52
So if your data is not normally distributed, then it is non -symmetrical.
00:57
So our non -symmetrical data can either be right skewed or it can either be left skewed...
