Question

For determining median from ogive curves ,

S1 : one can use less than type curve.

S2 : one can use more than type curve.

• A. S1 is true but S2 is false.
• B. S1 is false but S2 is true.
• C. S1 and S2 are true.
• D. S1 and S2 are false.

Answer 1

The correct option is C

S1 and S2 are true.

S1 is true.

Steps involved in finding median from less than type ogive curve are

(i) Draw the ogive curve for the less than type.

(ii) At cumulative frequency = $\frac{n}{2}$ , draw a horizontal line to intersect the curve at a point X.

(iii) From X drop a perpendicular to x-axis.

(iv) The point where the perpendicular intersects the x-axis is the median.

S2 is true.

Steps involved in finding median from more than type ogive curve are

(i) Draw the ogive curve for the more than type.

(ii) At cumulative frequency = $\frac{n}{2}$ , draw a horizontal line to intersect the curve at a point X.

(iii) From X drop a perpendicular to x-axis.

(iv) The point where the perpendicular intersects the x-axis is the median.
