Okay, for this question we are asked to find the mean median and mode.
00:06
Okay, it's pretty straightforward.
00:09
So the mean, another way to say the mean is the arithmetic mean.
00:18
Okay, so the arithmetic mean or average.
00:23
Well, that is just sum of items.
00:27
Okay, could you say some of items? some of data points whatever you want to say some of items over the number of items over the total number number of items okay and this should give us the mean all right so i have here that this would be 65 plus 70 plus 90 plus 1004 plus 90 plus 19 plus 126 and this is over one two three four five six that's six items now before i go ahead there is something i wanted i want to discuss every time you get a data they just set like this the first thing you really have to do is to rearrange them preferably in ascending order so before we've been touching any of this stuff this is what i'm going to do i'm going to rearrange this in a certain order okay i would arrange this in a sending order i would say this is 65 this is 78 this is 90 i see another 90 here i see 104 and i see 126.
02:13
So i've rearranged this.
02:16
In the same slightly something else we could do and the same topic or notes of preliminary stuff to do, you could also arrange them, you could also write it out in terms of in tabular form.
02:37
So i'll write here on this point the data, okay.
02:43
And i could do something of the sort as a frequency.
02:50
Okay.
02:51
Now you see that this is going to answer some questions.
02:56
It's going to answer the other questions, right? and so you could leave this for what we're talking about, the median and things of that sort.
03:06
But it's something that we could do now.
03:08
Or we could do later just wanted to point that out well i have that when i do this calculation here that this is equal to 92 .116 that's not 90s or 92 .967 okay it goes on and on so you could approximate this to be 92 .17.
03:39
Or 92 .2 .2.
03:41
You can also do that.
03:42
Alright.
03:44
It's also something you could do.
03:47
So this is the mean...
