Question

For each of the following variables, write N, O, I, or R.

a. _____ Gender
b. _____ The number of slices of pizza left over after a party
c. _____ Temperature measured on the Celsius scale
d. _____ Types of cars on the freeway
e. _____ Ranking classes from easiest to hardest
f. _____ Income earned each year

Answer 1

Answer:

a) N

b) R

c) I

d) R

e) O

f) R

Step-by-step explanation:

Types of data:

• Categorical data are of two types nominal(N) and ordinal(O).

• Nominal data are the non parametric data,

• Ordinal data are also non parametric data but they are ordered and position matter for ordinal data.

Interval(I) and ratio(R)

• Interval are void of absolute values, that is they can have negative value. Negative value for an interval variable makes sense.

• Ratio are the variable whose true zero exist.

a) Gender

This is a nominal data as the values are non parametric.

b) The number of slices of pizza left over after a party

The level of measurement is ratio as true zero exist for this variable.

c) Temperature measured on the Celsius scale.

The level of measurement for temperature is interval as true zero does nit exist and negative value makes sens.

d) Types of cars on the freeway

Level of measurement is ratio as true zero does not exist.

e) Ranking classes from easiest to hardest

This is ordinal variable as position matters.

f) Income earned each year

The level of measurement is ratio as true zero exists.
