22 children were asked whether they walked to school. 11 children said yes. What fraction of a pie chart would be taken up by the Yes segment?
- A.
One quarter
- B.
One third
- C.
One half
- D.
Total one
Correct Answer
C. One halfExplanation
If 11 out of 22 children said yes when asked if they walked to school, it means that half of the children said yes. Since a pie chart represents a whole, the yes segment would take up half of the pie chart. Therefore, the correct answer is one half.Rate this question:

In a survey of 18 children, 12 had brown eyes and 6 had blue eyes. What fraction of a pie chart would be taken up by the segment for blue eyes?
- A.
One quarter
- B.
One third
- C.
One half
- D.
Total one
Correct Answer
B. One thirdExplanation
In the given survey, there were 18 children in total. Out of these, 6 had blue eyes. To find the fraction of the pie chart taken up by the segment for blue eyes, we need to divide the number of children with blue eyes (6) by the total number of children (18). This gives us 6/18, which simplifies to 1/3. Therefore, one third of the pie chart would be taken up by the segment for blue eyes.Rate this question:

In one year, 300 Tourer bikes were sold. On a pictogram where 1 wheel represents 50 bikes, how many wheels would you put on the Tourer line?
- A.
1
- B.
6
- C.
300
- D.
500
Correct Answer
B. 6Explanation
The correct answer is 6. Since each wheel represents 50 bikes, and there were 300 bikes sold, we can divide 300 by 50 to find the number of wheels needed. The result is 6, so we would put 6 wheels on the Tourer line.Rate this question:

In a pictogram of favourite sandwich fillings, a face represents 4 children. The line for jam shows 7.5 faces. How many children prefer jam fillings?
- A.
30
- B.
28
- C.
7.5
- D.
75
Correct Answer
A. 30Explanation
The line for jam shows 7.5 faces. Since each face represents 4 children, we can multiply 7.5 by 4 to find the total number of children represented by the line for jam. This calculation gives us 30, so 30 children prefer jam fillings.Rate this question:

Which of these would be best at showing how the temperature of a pie changes over time when it is put in the oven?
- A.
Pie Chart
- B.
Line Graph
- C.
Bar Graph
- D.
All of these
Correct Answer
B. Line GrapHExplanation
A line graph would be the best at showing how the temperature of a pie changes over time when it is put in the oven. A line graph is ideal for displaying continuous data and can effectively represent the change in temperature over a specific period. It allows for a clear visualization of the temperature fluctuations, making it easier to understand the trend and pattern of the temperature change in the pie.Rate this question:

240 people were asked what they'd had for breakfast. A pie chart was drawn of the results. Toast took up one quarter of the chart. This shows
- A.
60 people had toast for breakfast

- C.
Most people like toast for breakfast
- D.
Least people like toast for breakfast
Correct Answer
A. 60 people had toast for breakfastExplanation
The answer "60 people had toast for breakfast" is correct because the pie chart shows that toast took up one quarter of the chart. Since there were 240 people surveyed, one quarter of 240 is 60. Therefore, 60 people had toast for breakfast.Rate this question:

What is it NOT important to do when looking at information in a bar chart?
- A.
Read the title and words on the chart to find out what it's telling you
- B.
Measure the width of each of the bars
- C.
Look carefully at the scale of the bar chart and read the height of each bar on the scale
- D.
All of the given points
Correct Answer
B. Measure the width of each of the barsExplanation
When looking at information in a bar chart, it is not important to measure the width of each of the bars. The width of the bars in a bar chart represents the categories or data being compared, and it does not provide any additional information or insight into the data. Instead, the title and words on the chart should be read to understand what the chart is conveying, and the scale of the bar chart should be examined to read the height of each bar, which represents the data values being compared.Rate this question:

- A.
Surveys
- B.
Experiments
- C.

Data sorting is a method of organizing and arranging data that has already been collected. It is not a method of collection itself. Surveys, experiments, and observations are all primary ways to gather data.Rate this question:

Lee made a bar chart to show how many bikes he sold each day. Each day had its own bar. We could find out the total number of bikes Lee sold by
- A.
Counting the number of bars
- B.
Finding the height of the tallest bar
- C.
Adding together the heights of all the bars in the chart
- D.
Reducing the number of bars
Correct Answer
C. Adding together the heights of all the bars in the chartExplanation
To find out the total number of bikes Lee sold, we need to add together the heights of all the bars in the chart. Each bar represents the number of bikes sold on a specific day, so by adding the heights of all the bars, we can calculate the total number of bikes sold. Counting the number of bars would only give us the total number of days, not the total number of bikes. Finding the height of the tallest bar would only give us the highest number of bikes sold on a single day, not the total. Reducing the number of bars is not a valid method for calculating the total number of bikes sold.Rate this question:

Tally marks are usually drawn in groups of
- A.
3
- B.
4
- C.
5
- D.
6
Correct Answer
C. 5Explanation
Tally marks are usually drawn in groups of 5. This is because tally marks are a simple way of counting and keeping track of numbers. Each tally mark represents one unit, and when you reach five tally marks, you draw a diagonal line across them to indicate a group of five. This helps in easily counting and organizing numbers, especially when dealing with large quantities.Rate this question:
