Steps: Count frequency of each number → Draw bars → Add labels

2. Which type of graph would be best for showing temperature changes over a week?

Bar graph

Line graph

Stem-and-leaf plot

3. Create a stem-and-leaf plot for these test scores:

65, 72, 78, 81, 85, 67, 73, 79, 82, 88, 69, 75

Steps: Group by tens (stem) → List ones digits (leaves) → Order leaves

📈 Part 2: Analysing Data

Use the pet data from Part 1 to answer these questions:

Data: 0, 1, 1, 2, 2, 2, 3, 3, 4, 1, 0, 2, 1, 3, 2

Mean = Total ÷ Number of values = _______ ÷ 15 = _______

5. Find the median (middle value) when data is ordered.

Ordered data: ________________________________

Median = _______

6. Find the mode (most common value).

Mode = _______

7. Which measure of central tendency best represents this data? Explain why.
8. If one student got 10 pets, how would this affect the mean?

Increase it significantly

Decrease it

No change

10. Complete this statement about your stem-and-leaf plot from Question 3:

Most test scores were between _______ and _______ marks.

The highest score was _______ and the lowest was _______.

11. When would you use each type of graph? Match each graph to its best use:
