Answer: Mean- 45
Median- 45
Mode- Nil
Range- 6
Step-by-step explanation:
Mean= sum of data set/number of data set= 42+43+44+45+46+47+48/7 =45
Median= arrange in an ascending order, then pick the middle data or number= 45
Mode- the number with highest frequency, in the case of this question, all number appeared once, hence no mode.
Range= difference between the highest and lowest value in a data set= 48-42=6
