Hello everyone we are going to solve a question in this question we are given this table and we have to find mean more than median.
00:07
So firstly we draw this table as here we have x that is middle value of this.
00:13
So middle value of this is 4 .5.
00:15
Here we have 14 .5 24 .5, 34 .5, 34 .5 and 44 .5.
00:24
Also here we calculate that this frequency is f.
00:30
So here we calculate fx.
00:32
So here we have 108, here we have 870, 980, 1690 .5 and 934 .5.
00:46
Also, we calculate the climative frequency.
00:50
That is the frequency remains firstly as it is.
00:53
Then we add 24 plus 60 in this like this.
00:57
When we come downwards, we add the frequency.
01:00
So 64 plus 60 is 84 then we add 40 in this here we have 84 then we have 40 so this is 124 then we add 49 this is 173 then we add 21 this is 194 now we find the sum of frequency that is equals to 194 and fx sum is 4583 so firstly we in this question we have to find to find mean, mode and median.
01:42
So firstly we find the mean here.
01:45
Mean is equals to formula for mean is summation of fx divided by summation of f.
01:52
So here this is 4, 583 divided by 194.
01:58
On solving this we have this is equals to.
02:01
23 .62, which is the final answer for mean of this question.
02:07
Moving ahead, we have to find the mode.
02:10
So, mode is equal to formula for mod is l plus f1 minus f0 divided by twice of f1 minus f2.
02:24
And here we have this is equal multiplied with h...
