1MA0 Higher November 2014 Paper 2 Q8
8 The frequency table gives information about the heights of some people.
| Height (\(h\) cm) | Frequency |
|---|---|
| \(160 \lt h \leqslant 165\) | 2 |
| \(165 \lt h \leqslant 170\) | 5 |
| \(170 \lt h \leqslant 175\) | 10 |
| \(175 \lt h \leqslant 180\) | 21 |
| \(180 \lt h \leqslant 185\) | 16 |
| \(185 \lt h \leqslant 190\) | 4 |
Draw a frequency polygon for this information.
(2)
| Answer | Mark | Notes |
|---|---|---|
| Polygon drawn | 2 | B2 for fully correct frequency polygon - points plotted at the midpoint (B1 for all points plotted accurately but not joined with straight line segments) or all points plotted accurately and joined with last joined to first to make a polygon or all points at the correct heights and consistently within or at the ends of the intervals and joined (can include joining last to first to make a polygon) NB: ignore parts of graph drawn to the left of the 1st point or the right of the last point; ignore any histograms drawn. |
