OpenStudy (vshiroky):

I'm confused on the whole thing I have a couple more that I am unsure of too

Are you able to help me?

OpenStudy (compassionate):

Nominal; (of a role or status) existing in name only.

OpenStudy (vshiroky):

ok so for this one A researcher measures level of educations as: "Less than high school", "High School", "Some college", "College graduate". This is what scale of measurement? Nominal?

OpenStudy (vshiroky):

A bank asks customers to evaluate the drive-thru service as good, average, or poor. Which scale of measurement is this? Nominal as well?

OpenStudy (vshiroky):

sorry if I'm bugging you @Compassionate I want to double check my answers

_________________________________________________ The nominal level of measurement is the lowest of the four ways to characterize data. Nominal means "in name only" and that should help to remember what this level is all about. Nominal data deals with names, categories, or labels. Data at the nominal level is qualitative. Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement. Even some things with numbers associated with them, such as a number on the back of a football jersey, are nominal since it is used to "name" an individual player on the field. _________________________________________________ _________________________________________________ The ordinal type allows for rank order (1st, 2nd, 3rd, etc.) by which data can be sorted, but still does not allow for relative degree of difference between them. Here you should think of things like a list of the top ten cities to live. The data, here ten cities, are ranked from one to ten, but differences between the cities don't make much sense. There's no way from looking at just the rankings to know how much better life is in city number 1 than city number 2. _________________________________________________ _________________________________________________ The interval level of measurement deals with data that can be ordered, and in which differences between the data does make sense. Data at this level does not have a starting point. The Fahrenheit and Celsius scales of temperatures are both examples of data at the interval level of measurement. You can talk about 30 degrees being 60 degrees less than 90 degrees, so differences do make sense. However 0 degrees (in both scales) cold as it may be does not represent the total absence of temperature. _________________________________________________

What is the scale of measurement? Interval ratio A doctor measures the waist (in cm) of a number of patients. This would be which scale of measurement? Interval ratio

OpenStudy (compassionate):
