Mathematics
On a graph paper, draw histogram (taking suitable scales) for the following data and then using histogram drawn, find the mode :
| Monthly wages | No. of workers |
|---|---|
| 1850-1900 | 32 |
| 1900-1950 | 64 |
| 1950-2000 | 84 |
| 2000-2050 | 100 |
| 2050-2100 | 70 |
Answer
Steps :
Draw a histogram of the given distribution.
Inside the highest rectangle, which represent the maximum frequency (or modal class), draw two lines KN and LI diagonally from the upper corners K and L of adjacent rectangles.
Through the point Q (the point of intersection of diagonals), draw QR perpendicular to horizontal axis.
The value of point R on the horizontal axis represents the value of mode.
∴ Mode = 2015 (approx)
Hence, mode = ₹ 2015 (approx).
