It has overlapping numbers.		1
Some numbers appear twice.		1
Should be 0-5, 6-10 etc.	or 0 – 4 then 5 – 9 etc	1
Should be \(0 \leqslant h \lt 5\), \(5 \leqslant h \lt 10\) etc	Condone \(0 \lt h \leqslant 5\), \(5 \lt h \leqslant 10\) etc	1
The labels for the bars overlap		1bod
10 is in both sets	Repeated value	1
the age is confusing because there’s 2 bars that 10 can go into	Repeated value	1
The age section of the graph use the previous number in each bar.	Repeated value	1
he uses the same age twice	Accept BOD to mean value repeated in two groups	1
he doesn’t need to put the same number that was at the end in the beginning	BOD repeated value	1
Some people could claim to be in two different bar charts (5, 10, 15)	BOD inclusion of charts and intention 5 – 10 and 10 - 15	1
Should be \(0 \leqslant h \leqslant 5\), \(5 \leqslant h \leqslant 10\) etc	This does not resolve the issue of overlapping values	0
it didn’t have to go up in two’s as the number of people attending were all odd	False	0
you should not go if your 0 – 5 as it is very young to go to a youth club	Irrelevant	0
the bars aren’t all the same width	They are	0
The age gaps are too big	No criticism of the end points of the scale	0
There are gaps between the bars		0
Age doesn’t start at 0.		0
The categories could be more specific/are not accurate.		0
Some young people are older than 20.		0
Age is not a linear scale		0
