(b) On the grid below, draw a bar chart for this information.

A blank grid, 10 squares wide and 10 squares high, with a horizontal and a vertical axis and no labels or scale

(3)

Mark scheme (a)

Answer	Mark	Mark scheme
Correct frequencies 8, 3, 5, 2	B2	all frequencies correct
Correct frequencies 8, 3, 5, 2	(B1	Starts to work with tallies, eg 2 tallies fully correct, or 2 frequencies fully correct)

Additional guidance

Correct tallies alone scores B1
Correct frequencies with no tallies scores B2

Tallies need not be crossed

Mark scheme (b)

Answer	Mark	Mark scheme
Bar chart	M1	for labelling pet names on the horizontal axis or bars OR a linear scale on the vertical axis.
	M1	for at least two correct bars ft their table in (a)
	A1	for a fully correct bar graph ft from their frequencies or tallies in (a).

Additional guidance

For the first M1: Accept unambiguous abbreviations for labels, eg D, R, C, H
Horizontal axis does not need “pet” label

For the second M1: Condone bars of unequal width
Condone no gaps or inconsistent gaps
Bars must be unambiguously correct for their scale

For the A1: All four bars must be correct with labels, ft, to award this mark.
Vertical axis must have a suitable label, accept unambiguous abbreviations, eg freq or number
Condone no gaps, or inconsistent gaps.
Condone bars of unequal width
Horizontal axis does not need “pet” label
