The 'less than' ogive and the 'more than' ogive of a distribution of daily sales (Rs thousand) are drawn on the same graph. What does the x-coordinate of their point of intersection give?

The x-coordinate where the 'less than' and 'more than' ogives intersect is the median. At that point the cumulative frequency below equals the cumulative frequency above, each being half of the total observations. The mean and mode cannot be read from this intersection.

  2. BThe medianCorrect
  3. CThe mean
  4. DThe range

Explanation

At the intersection, the number of observations below the value equals the number above it, each being N/2. That value is the median. The mean and mode are not located by this intersection, and the range is simply the difference between extremes.
