Hello students we need to find here mean value and median value right so we all know data is given so mean is sum of data divided by total number of data so number of data if we are going to write this so let's write for sum of data which is 5 .5 plus 3 .4 plus 9 .5 plus 4 .5 plus 4 .5 dot dot 2 .5 and total values are 1, 2, 3, 4, 5, 6, 7, 1, 2, 3, 4, 6, 7, 8, 9, 10, which is divided by 10.
00:41
So let's write all the values which is 52 .4 divided by 10, 5 .24, right? so finally, we need to find for median.

So for median, we need to, we need to arrange data in, ascending or descending order right ascending or descending order so if i write for it so let's arrange all the value in ascending order what is ascending order from smaller to larger values so we need to write here all the ascending water values as 2 .3 2 .5 3 .4 3 .4 and again 3 .4 next next value is 4 .5 and again 5 .5 and this is 5 .7 and next value is 6 .7 and 8 .9.

Right.
01:48
So here number of terms are even which is 10.
01:52
So median is for even terms n by 2 the term n by 2 the term plus n by 2 plus 1th term if we are going to write this n by 2 plus 1 the term right and whole is divided by 2 if we are going to write this this 5th term plus 6th term and this is divided by 2 so here this is divided by 2 but we need a missed term here which is 9 .5 we need to add this term to so it is 9 .5 now 10 terms so 5th term is 1 to 3 4 .5 and 5 .5.

So 4 .5 plus 5 .5 divided by 2...
