Here i have to make an ordinary frequency table from the cumulative frequency table.
00:04
So let's write this down.
00:06
So from the cumulative i need to make ordinary.
00:12
Let's make a sketch.
00:14
Let's make the first column, column marks below.
00:19
The second one is the cumulative frequency and first to mark below 10, then 20, and the frequencies are 3 and 8 respectively.
00:30
Now let's write down the column for just frequency.
00:34
So for the first one, the frequency is still 3.
00:37
But for the second one, the frequency is 8 minus 3, which is 5.
00:44
Next one is below 30...
