4.6 4.5 4.7 4.5 4.5 4.6 4.6 4.6 4.8 4.6 )

(a) Arrange the data into equal classes

(b) Determine the frequency distribution

(c) Draw the frequency histogram

(d) Create a cumulative frequency table for the data

(e) Draw the cumulative frequency graph

(g) Calculate: i) the mean and standard deviation; ii) the upper and lower quartile values; and iii) the interquartile range for the given data.

2. use to the data to :

(Force (N) 0 20 40 60 80
