Measurement--$100

A variable representing an interval that can be broken down into infinite fineness

answer

Measurement--$200

Of the four scales of measurement, the most sophisticated

answer

Measurement--$300

This scale indicates > or < but not by how much

answer

Measurement--$400

Many scales constructed to measure psychological attributes for research purposes (e.g., IQ and extroversion) are measured on this type of scale

answer

Measurement-$500

A ______ scale consists of unordered, separate categories and is depicted graphically with this type of figure/graph

answer

Strategies & Designs--$100

The goal of this research strategy is to establish a cause-effect relationship.

answer

Strategies & Designs --$200

The goal of this research strategy is to describe the relationship between two variables as they naturally occur in the environment.

answer

Strategies & Designs --$300

A researcher manipulates this variable because it is the presumed cause of behavior.

answer

Strategies & Designs --$400

This results when other variables are allowed to vary systematically with the independent variable, leading to ambiguous results.

answer

Strategies & Designs --$500

This type of variable is treated like an independent variable statistically but it was not manipulated by the experimenter.

answer

Frequency Distributions--$100

The simplest frequency distribution consists of these two columns.

answer

Frequency Distributions --$200

The shape of a _____ distribution is perfectly symmetrical.

answer

Frequency Distributions --$300

This is the appropriate type of chart (or visual) for discrete data.

answer

Frequency Distributions --$400

These two types of charts appropriately represent data from continuous variables.

answer

Frequency Distributions --$500

A mathematical procedure for estimating a value that is located between two known values.

answer

Descriptive Stats--$100

A statistical measure that determines a single value that accurately describes the typical score of a distribution.

answer

Descriptive Stats--$200

This measure of central tendency is the score at the 50th percentile.

answer

Descriptive Stats --$300

This measure of variability measures the average distance between scores and the mean.

answer

Descriptive Stats --$400

This measures the average of the squared distances from the mean.

answer

Descriptive Stats --$500

In order to calculate this, take the square root of the population variance.

answer

Grab Bag--$100

The type of correlation that indicates an inverse relationship between two variables.

answer

Grab Bag--$200

In statistical formulas, N represents ______________.

answer

Grab Bag--$300

The only appropriate measure of central tendency for data measured on a nominal scale.

answer

Grab Bag--$400

Percentile ranks correspond to the values in the ______ column of a frequency distribution

answer

Grab Bag--$500

The sum of the deviations from the mean always equals this.
