The systematic component is ______ and the random component is _____

A disadvantage of non-probability sampling is…

Convergent validity is a type of construct validity that is established when…

Regressions allow us to….

Random error =

Y’ =

When test anxiety is not related to statistics anxiety but may effect performance. This is a…

A survey is________ if it measures the same construct repeatedly

R2 is the squared value of the correlation and used to ……

What are the 3 components of observed scores?

b0 represents…

The primary goal of ________ is statistical estimation eg what is the prevalence of food addiction in QLD?

How does precision effect the standard deviation?

Cross-sectional surveys are _______

________ looks at the relationship between one predictor variable (IV) and one outcome variable (DV)

In bivariate regression ________ is the same as the correlation (R)

____________ the difference between actual scores and predicted scores

______ is when a researcher makes a judgement on sample selection based on their expertise

Sample ______ influences precision

The presence of low correlations between the measure and measures of unrelated constructs eg depression & intelligence =

_____ when important subgroups of a population are over or under represented in the sample.

The difference between prediction scores and actual scores is

Research questions from this approach ask about prevalence rates or “descriptive hypotheses”

The standard deviation of the distribution of samples means is referred to as:

b1 represents

What is the above equation?

What is the above equation?

____________ the amount of total variance explained by the improvement in prediction by the regression line.

Sample _______ will influence bias

What is NOT a type of non-probability sampling

What is NOT a type of probability sampling

Probability sampling is based on…

Psychologists use the _______

Leading and loaded questions may cause…

The _____ is the rate at which Y changes with each one-unit change in X

What is the above equation?

Longitudinal or panel surveys are _______

Content validity…

We create dummy variables when….

The _______ is the predicted value of Y when X = 0

An advantage of probability sampling is…

______ score is the systematic effect of the underlying construct

You can assess internal consistency with:

_____ uses non-random approaches eg students who attend tomorrows 2pm lab class

______ is the extent to which items on a measure asses the same construct.

Samples fail to provide good estimates of a population for two reasons:

_______ is used to add in reliability to data

Constructs are typically…

________ restate the score in terms of its distance from the mean

We use ________ to ensure the subset of the population we select is representative

A survey is _____ if it measures the construct it was designed to measure.

When the measure assesses only the characteristics it is designed to measure =

The _______ measures the strength and direction of the association

Beta Weights are the _______

_________ use sample data to make inferences about a population

________ is interested in the deviations of all scores from the mean of Y

The _______ helps us to improve prediction

A potential problem with survey day when a participant hides attitudes or biases is…

_____ is the stability of a measure across time.

______ test specific theories or hypotheses about the relationship between variables. Eg “what is the mechanism”

These research questions look to discover mechanisms or test specific hypotheses about relations between variables

A class list, electoral role and phone book are examples of…

____ is based on coverage of the correct underlying construct & how well a measure assess the construct.

In sampling __________ = higher precision
