How do you find CF?

The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors. The last value will always be equal to the total for all observations, since all frequencies will already have been added to the previous total.

How do you plot a cumulative frequency graph?

Why is the sum of all relative frequencies equal to 1?

For a ratio of 1:1, there are two total outcomes, so the relative frequency of heads is ½ or 0.5 and the relative frequency of tails is the same. The sum of relative frequencies is also equal to one, since the sum of all fractional parts must equal the whole.
