There are some given data here and we have to calculate the mean.
00:04
So let's just write, let's say, the weight, and this is say the x value, and the data that is given as the y value here.
00:16
So that is 5 .53 and 7 .07 and 4 .20.
00:25
The next point is 1 .18 and 4 .27.
00:31
Next one is 3 .57 so the next one is 2 .06 and the next one is 5 .08 and related data value here is 2 5 410 this is 410 282 to 8 2 and 10 so for the mean value what we have to do we have to just multiply and divide the total number of data here so that is 2 times 5 .53 plus up to, let's say, 10 times 5 .08, and divided by the total number of values here.
01:14
12, 20, 20, 20, 32, 36.
01:17
This is 36.
01:19
41, 43.
01:21
So we have to divide by 43.
01:23
So we can do this by the calculator.
01:25
Let me just show you how you also do this calculation with the calculator.
01:28
If you are using the ti 84, just press the button instead and then the edit calculation.
01:35
So we have to just put the numbers on the table here...
