Question statement

A random sample of 20 residents from Newcastle were asked about the number of times they went to see a play at the theatre last year.

Here is the list of their answers:

$\var{a[0]}$	$\var{a[1]}$	$\var{a[2]}$	$\var{a[3]}$	$\var{a[4]}$	$\var{a[5]}$	$\var{a[6]}$	$\var{a[7]}$	$\var{a[8]}$	$\var{a[9]}$
$\var{a[10]}$	$\var{a[11]}$	$\var{a[12]}$	$\var{a[13]}$	$\var{a[14]}$	$\var{a[15]}$	$\var{a[16]}$	$\var{a[17]}$	$\var{a[18]}$	$\var{a[19]}$

Give any introductory information the student needs.

			Name	Type	Generated Value

a	list	List of 20 items
a_s	list	List of 20 items
range	number	8
modetimes	list	[ 2, 3, 6, 1, 4, 1, 0, 1, 2 ]

			Name	Type	Generated Value

Description

The final list.

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `list`

[ 2, 2, 8, 4, 1, 4, 2, 3, 2, 2, 1, 7, 2, 4, 0, 4, 8, 0, 1, 5 ]

← Depends on:

This variable doesn't seem to be used anywhere.

Advice

Range is the difference between the highest and the lowest value in the data.

To find this, we subtract the lowest value from the highest value:

\[ \var{max(a)} - \var{min(a)} = \var{range} \text{.}\]
