Worked practice questions

A "less-than" ogive is plotted with which values on the y-axis?

  1. class boundaries
  2. individual frequencies
  3. cumulative frequencies
  4. class marks
Show answer and solution

Correct answer: C. cumulative frequencies

Less-than ogive: x-axis carries upper class boundaries y-axis carries less-than cumulative frequencies.

The x-coordinate of the point where the less-than and more-than ogives intersect equals the:

  1. mean
  2. range
  3. mode
  4. median
Show answer and solution

Correct answer: D. median

At the intersection, both cumulative counts equal n/2 — by definition, that x-value is the median.

On a less-than ogive, the median is read off by drawing a horizontal line at:

  1. y = n/3
  2. y = n/2
  3. y = n/4
  4. y = n
Show answer and solution

Correct answer: B. y = n/2

Median splits the data in half — so the horizontal line is at y = n/2, and the x-intercept where it meets the curve is the median.
