24 The table shows information about the heights of 50 trees.
| Height (\(h\) metres) | Frequency |
|---|---|
| \(0 \lt h \leqslant 4\) | 8 |
| \(4 \lt h \leqslant 8\) | 21 |
| \(8 \lt h \leqslant 12\) | 12 |
| \(12 \lt h \leqslant 16\) | 7 |
| \(16 \lt h \leqslant 20\) | 2 |
Draw a frequency polygon for the information in the table. (2)
| Answer | Mark | Notes |
|---|---|---|
| Polygon drawn | 2 | B2 for correct frequency polygon (B1 for points plotted at correct midpoints of intervals or joining points at correct heights consistently within intervals including plotting at end values or correct frequency polygon with one point incorrect or correct frequency polygon with first and last points joined directly) NB ignore any histogram drawn and any part of frequency polygon outside range of first and last points plotted |
