Question 1 · 1 mark · Difficulty 1/3

Why do the bars of a histogram touch one another?

  1. Because the bars are always the same width
  2. Because it looks neater that way
  3. Because the frequencies are always equal
  4. Because the data is continuous, so one class ends where the next begins
Show answer & explanation
✓ Answer: D — Because the data is continuous, so one class ends where the next begins
A bar chart shows separate categories with nothing between them, which is why its bars are drawn apart.
Question 2 · 1 mark · Difficulty 1/3

How is the midpoint of a class found?

  1. Add the two boundaries together
  2. Subtract the lower boundary from the upper boundary
  3. Add the two boundaries and divide by two
  4. Divide the upper boundary by two
Show answer & explanation
✓ Answer: C — Add the two boundaries and divide by two
Subtracting them instead gives the class width, which is a different quantity.
