We've collected the following data points --
- {data point of #4}
- {data point of #1}
- {data point of #7}
- {data point of #8}
- {data point of #1}
Let's find the average of these values. We've got a tally running, we
should continue accumulating values --
: {there are $count data points}
{data point of $x} {sum is $n}
>
{@add $count and #1 into &"there are * data points"}
{@add $n and $x into &"sum is *"} :
: {data point of $x}
>
{there are #1 data points}
{sum is $x} :
When we are out of data points to tabulate, we can finally compute the
average --
: {there are $count data points} {sum is $sum}
>
{@divide $sum by $count into &"the average is *"} :
Write out the finaly result to the console --
: {the average is $average}
>
{@write "The average is "}
{@write $average}
{@write ".\n"} :
