Question

The median of the data set represented by the stem-and-leaf plot is


Height of plants (in m) \begin{tabular}{r|lll} \hline Stem & \multicolumn{2}{|c}{ Leaf } \\ \hline 1 & 5 & 7 & 8 \\ 2 & 4 & 6 & 9 \\ 3 & 7 & \\ & & \\ \cline { 3 - 4 } & Key \( 1 / 5=1.5 m \) \end{tabular}

• A. 2.9 m
• B. 2.6 m
• C. 2.4 m

Answer 1

The correct option is C 2.4 m

From the given stem-and-leaf plot, we find:

Key: 1|5 = 1.5 m



The data set is

1.5, 1.7, 1.8, 2.4, 2.6, 2.9, 3.7.

Arranging them in ascending order, we get


Hence, the median is 2.4 m.
