Which of the following variables is Nominal? Select one: a. Age (in years) b. Age (grouped as: less than 18, 18-29, 30-59, 60 an
Arada [10]

Answer:

c. Car color (e.g. red, blue, grey)

Step-by-step explanation:

There are four level of measurements: Ordinal, Nominal, Interval and Ratio.

  1. Ordinal variables are categorical variables and have a ordered categories. For example,the health of patients: Excellent, Good, Average and Poor.
  2. Nominal variables are also categorical variables but they do not have a ordered category or any numerical value. For example, Gender: Male or Female, or Occupation:, Accountant, Clerk, Manager.
  3. Interval variable are variables that take numerical values. These variables are ordered and  the difference between two values is meaningful. For example, temperature in degrees F.
  4. Ratio variable are type of interval variables but they do not have a variables with a 0 measurement. For example, height, age, money.

Considering all the option:

(a) Age (in years) is an interval variable.

(b) Age grouped as < 18, 18 - 29, 30-59, 60 > are basically ordered categorical variables. Thus, they are ordinal variables.

(c) Car Color (red, blue, grey) are nominal variable because they are not ordered and cannot be measured.

(d) Letter grade in a course (A+, A, A-, B+, B) are also ordinal variables because they are ordered and represent the performance quality of the student.

Thus, the correct answer is (c).

Slope 0, passes through (0, –10)
Alecsey [184]
Answer:
y=-10

Explanation:
The answer choices are all in slope-intercept form, which is this equation:

y=mx+b

Here’s what the variables mean:

Y=the y axis
M=the slope
X=the x axis
B=the point on the line that intercepts the y axis (the y-intercept)

We know the slope is 0, so 0 would be the m variable.

y=0x+b

We also know that the line passes through (0,-10), which means the y-intercept is -10.

y=0x+(-10)

0 multiplied by anything equals 0 and a negative and positive makes a negative, so we can rewrite the equation to be this:

y=-10

I hope this helps! Please comment if you have any questions.
