Score: Week 1. Measurement and Description - chapters 1 and 2<1 point> 1 Measurement issues. Data, even numerically coded variables, can be one of 4 levels -

such as means can only be done on interval or ratio level data.
Please list under each label, the variables in our data set that belong in each group.
Nominal Ordinal Interval Ratio
Gender Degree Performance Age
Gender 1 Grade Rating Salary
Degree Service
b. For each variable that you did not call ratio, why did you make that decision?
In my opinion the variables are not what
you would describe as a ratio, My reasoning
is because ratio data should be a positive
number and a number that reaches 0 ceases
to prevail as a ratio.

c. Why are the results different?
The results are different because overall a sample is taken from the entire group of 50 peopl
and Female the fields are narrowed to 25 per person in each ratio.

a. The value that cuts off the top 1/3 salary in each group.

What is the difference between the sal and compa measures of pay?
Based on the data given I see that males are receiving more salary compared to female work
rates, in some cases it does appear that both male and female workers are getting paid a high
that being said both have compa ratio greater than one.
Conclusions from looking at salary results:
In my opinion based on the data presented I can conclude that the range of all three groups a
are no major discrepancies amongst any of the groups which indicates a normal falsehood.
Conclusions from looking at compa results:
After reviewing the compa results once more, I can say that the overall, female workers, and
indicates that the workers salaries are being paid above the normal salary within the industry
Do both salary measures show the same results?
