A theatre owner asked 20 Grade 6 students buying a movie ticket how many movies they see each month. The chart shows the results.

a) Organize the data into a tally chart with intervals.

b) Sketch a graph to display the data. Justify your choice of graph.

c) Would the results of the survey represent adults in the neighbourhood? Explain your reasoning. Q1

a) Plot the coordinate pair (4, 5) on a grid.

b) Draw a 2 unit by 2 unit square with the point (4, 5) in the middle. List all points that are on the perimeter of the square. Q2

A bug starts at a corner of this rectangle drawn on centimetre dot paper. It crawls clockwise around the rectangle until it ends up back at the start. The table shows the distance travelled from the start and the distance it had left to travel at each corner.  a) Compare distance travelled to distance to go.

b) Describe the shape of the line graph.

c) How far had the bug moved from the start when it had 3.5 cm left? Use the graph.

Q3

Mika’s Grade 6 class measured the leg length and height of each student. The table shows the data. a) Compare leg length to height. Use a scatter plot.

b) Do taller students usually have longer legs? Use the scatter plot to justify your reasoning.

Q4

Chelsea recorded the amount of sugar in a 30 g serving of each of 20 cereals. Ten were marked Kids’ Cereal and ten were marked Family Cereal.

a) Determine the median amount of sugar in each set.

b) Which type of cereal typically has more sugar? Q5

Determine the mean and the median of each set of data.

3,13,15,15, 17, 22, 24, 32,33, 34, 89

Q6a

Determine the mean and the median of each set of data.

7,9,5, 7,9,5,9,13

Q6b

Determine the mean and the median of each set of data.

41, 106, 97, 348, 8

Q6c

Determine the mean and the median of each set of data.

31, 77, 55, 44, 22, 77

Q6d

The line graph shows the mean height of children at each age from 2 to 11 years.

a) Why did the scale on the vertical axis start at 80 cm instead of 1 cm?

b) Predict the appearance of the line graph if the scale on the vertical axis changed from 1 unit for 10 cm to 1 unit for 5cm.

c) Explain how the appearance of the graph would change if the scale on the vertical axis changed from 1 unit for 10 cm to 1 unit for 20 cm.

d) How can you use the graph to estimate the mean height of 12-year-olds?

e) How can you use the graph to estimate the mean height of 8.5-year-olds’?
