to classify the type of data being collected)
,What type of scale is used when labeling or using categories? -
ANSWER ✔✔This would be qualitative data and the SCALE would
be nominal! Ex: blood type, college majors, room numbers
True or false: it is generally feasible to collect data from every member of
a population - ANSWER ✔✔FALSE! unless the target of a particular
research study is comprised of a small population, it is usually not
practical or sensible to attempt to reach every member within a
population
Which of the following are examples of ordinal variables? Select all that

- Shirt sizes
- college major
- places in a marathon (1st, 2nd, 3rd)

median, mode, standard deviation, variance, and range. Inferential
statistics involve calculations such as those use for hypothesis testing
(z-scorem, t-test, ANOVA, correctional analyses).
