O Marketing O Maintenance O Finance O Production O Servicing O Personnel O Sales O Public Relations O Accounting What is your gender? O Male O Female For the gender we categorized into two groups and we assign number for each male 1 and female 2 to label each of these groups,, the nominal scale allows us only to qualitatively distinguish groups by categorizing them into mutually exclusive and collectively exhaustive sets The information generated from nominal scale help us in calculating the frequency of male and female in our sample respondents Dr. Sami 5

Ordinal Scale Ordinal scale: not only categorizes variables in such a way as to denote differences among various categories, it also rank-orders categories in some meaningful way. Use to differentiate the categories and provide information on how respondent distinguish them by ranking-order them. Example: what is the problem you face in UUM? You may sign number 1 for the most important than 2 to the less, 3 more less and so on ,,,, What is the highest level of education you have completed? O Less than High School O High School/GED Equivalent O College Degree O Masters Degree O Doctoral Degree Dr. Sami 7

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
