# Find the Mean for the Following Frequency Distribution: - ICSE Class 10 - Mathematics

ConceptMeasures of Central Tendency - Mean, Median, Mode for Raw and Arrayed Data

#### Question

find the mean for the following frequency distribution:

 C.I 0-50 50-100 100-150 150-200 200-250 250-300 Freq 4 8 16 13 6 3

#### Solution

 Class interval Frequency (f) Cclass mark(x) fx 0-50 4 25 100 50-100 8 75 600 100-150 16 125 2000 150-200 13 175 2275 200-250 6 225 1350 250-300 3 275 825 Total 50 7150

Mean= (∑fx)/(∑ f) =7150/50=143

Is there an error in this question or solution?
