Question
I just need an explanation with the answers on numbers 4-6. Thanks
In a recent advertisement, Gillette claimed that their new Crazy Daisy shaver shaves legs smoother, closer, and safer than any other single-blade disposable razor for women. After shaving each leg with a different razor (Crazy Daisy versus the Lady Bic) according to their own routine, women rated each shaver on smoothness, closeness, and safety. A composite score of those three attributes ranging from 1-10 was used to test for overall average group differences. Assume the experiment was conducted three different times with three different groups of women. Answer the questions for each experiment using the following output. What type of variables were used in the study (qualitative or quantitative/discrete or continuous)? Razor ____ _____ Score _____ _____ What level of measurement were the variables on? Razor _____ Score _____ Were the samples independent or dependent? _______Explanation / Answer
4) The classification of razor is not on countable numbers but on labels such as Crazy Daisy and Lady Bic, thus, razor is qualitative, discrete variable.
The classification of score is done on the number range 1 - 10 and hence countable, thus, score is quantitative, discrete variable.
5) The variable razor is classified into labels which can neither be measured nor ordered, thus, razor is on nominal scale of measurement.
The claasification of variable score is done on the numeric order range 1 - 10, thus score is on ordinal scale of measurement.
6) The samples are independent of each other.
