Answer 1

Answer:

Arranging the data in tabular form, we get: Therefore median = ((n+1)/2)th term Median = value of 13th term Median = 163 cm Here, clearly, 163 cm occurs the most number of times. Therefore, the mode of the given data is 163 cm. Mode = 3 Median – 2 Mean 163 = 3 x 163 – 2 Mean 2 Mean = 326 Mean = 163
