00:01 So our question says for the distribution here, identify the main, the median and the mode.

00:05 So before we pick the right answer, we need to resketch the distribution in our worksheet.

00:11 So we have something of this nature and we have this to be skewed towards the left.

00:18 So we have the horizontal axis and as you can see on our horizontal axis rather the values of x is going to be increasing towards the right so meaning we can be having number one here we have number two here we have number three and probably number 10 or something you write here so the point i'm trying to make is that across the horizontal axis as you move towards the right of the horizontal axis the values right there actually increases so we have three lines we have line here we have this line here and we have this line here uh in accordance to our question we call this line line c we call this b and we call this a okay let's clean of this so that been said we need to know something our data set is not symmetric in fact this is a skewed data set that is most of the data falls or cluster around a specified region in the distribution so as you can see the tail of the data actually falls towards the left it's pointing towards a left this is a tail and it is pointing towards the left since the tail is pointed towards the left it simply implies that we have a call a negative skewness that is this distribution of us is defined by a negative skinness we are going to be having a negative skewness coefficient now we have what we call the piercings formula are the piercing skewness coefficients and this is actually the value that we used to define the skewness of a distribution now the piercing skewness coefficient is given as pse and it has a formula that says 3 into bracket the mean minus the median divided by the standard deviation so for us to have a negative piercing skewerness coefficient it simply implies that the median must be greater than the mean in other words it means that the mean is going to be lesser than the median now of the lines here the of the lines right here cba the line with the list value is going to be c.

02:39 So that simply means that our c is going to be the mean.

02:43 B is going to be the median.

02:47 And our a is going to be the mode...

Question

For the distribution drawn here, identify the mean, median, and mode. C B A A = mode, B = median, C = mean A = median, B = mode, C = mean A = mode, B = mean, C = median A = mode, B = mean, C = median
