We have been given some data and we want to turn it into a relative frequency distribution.
00:06
So we need a column for the categories.
00:11
So it's our monday, tuesday, wednesday, thursday, saturday, and make some space, sunday.
00:23
Then we need a column for the frequencies and those have been given to us.
00:36
So the frequencies are 52, 64, 71, 55, 62, 44 and 52.
00:49
So these are the numbers of babies born on each of these days.
00:53
How do we turn it into relative frequency? so the relative frequency is equal to the frequency divided by n, the number of pieces of data.
01:04
What is n here? well, all we need to do is add up these frequencies, and we will get the total number of babies born in this week.
01:12
So i'm just adding these up to get 400.
01:20
And this formula gives the proportion.
01:25
So this gives the proportion, and that's in decimal form.
01:32
It tells you the proportion of the babies born on each day...
