What is the ratio scale?

A

Order matters, = distance between units, true zero, allows there to be ratio comparisons of values, length/weight/time/temperature

79
Q

What are the levels of measurement?

A

Nominal: named
Ordinal: named, natural order
Temperature: named, natural order, =interval between variables
Ratio: named, natural order, =interval between variables, has a “true zero” between values can be calculated

80
Q

What are outliers?

A

Values that are inordinately small or large given as much weight in determining mean as any other score, pulls the mean

81
Q

What is standard deviation?

A

Measure of data dispersion, relative to the mean, how far score is from mean

82
Q

What is variance?

A

How much spread in data

83
Q

What is range?

A

Number of possible values for scores in data set, does NOT indicate how data is distributed (subtract HS from LS)

Q

What are correlations?

A

Degree and direction of relationship between variables, r-value: -1 to +1, farther from 0

85
Q

Valid but not reliable
