Explanation / Answer
Solution :
(a) From Given information,to construct a relative frequency distribution table
=> Total frequency n = 420 + 422 + 953 + 411 + 70 = 2276
=> Relative frequency = f/n
Response Frequency Relative frequency
Never 420 420/2276 = 0.185
Rarely 422 422/2276 = 0.185
Sometimes 953 953/2276 = 0.419
Most of the time 411 411/2276 = 0.181
Always 70 70/2276 = 0.031
(b) The percentage of respondents answered "always" is
=> relative frequency * 100
=> 0.031*100
=> 3.1%
(c) The percentage of respondents answered "Never" or "Rarely"
=> 0.185*100 + 0.185*100
=> 37.0%
(d) => Option B. frequency bar graph
(e) => Option A. relative frequency bar graph
(f) => Option B. pie chart
(g) => Option A. inferential
