Answer #1

There are six variables in the survey.

Please find below the table with the level of measurement for each variable.

Variable Level of Measurement
Gender Nominal Contain names and qualitative scales.
Height Ratio Ratio scales can be described as specifying "how much" of something (i.e. an amount or magnitude) i.e. quantitative.

Last year math grade (A, B, C, D, F)

 Ordinal The ordinal type allows for rank order (1st, 2nd, 3rd, etc.) by which data can be sorted.
Number of close friends Nominal Because having grouping and membership properties.
School grade point average Ratio Quantitative
Marital status of parents Nominal Classification

In a certain high school, uniforms are optional. A study shows that high school students who wear uniforms have a lower grade average than students who don't wear uniforms. From this study, the school administration claims that they should not require the students to wear uniforms because that is the cause of the lowering grades. Another possible explanation is that students who wear uniforms are poorer than the students who don't wear uniforms and the economic situation of their parents...

The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.2% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full-time freshmen from the survey. You are interested in the number that believes that same-sex couples should have the right to legal marital status. Construct the probability distribution function...
