Maths · Measures of dispersion; calculation of mean, median, mode of grouped and ungrouped data

The lower limit of the modal class of the following data is : Frequency 13 7

The lower limit of the modal class of the following data is : \( \begin{array}{lllll} & 0 & 10 & 20 & 30 \\ \text { c.l. } & - & - & - & - \\ & 10 & 20 & 30 & 40\end{array} \) Frequency \( \quad 5 \quad 8 \quad \) 13 \( \quad \) 7

  • A. 10
  • B. 30
  • C. 20
  • D. 50

Step-by-step solution

The modal class is the class interval with the highest frequency. Here, frequencies are 5, 8, 13, 7 for class intervals 0-10, 10-20, 20-30, 30-40 respectively. The highest frequency is 13, corresponding to the class 20-30, so its lower limit is 20.
