Module 2 -1 Practice Questions

Front

What does 'strong curvilinear' relationship mean?

Back

A strong curvilinear relationship indicates that as one variable increases, the other variable changes in a non-linear manner, showing a clear pattern that is not a straight line.

Front

What is the difference between 'case C -> Q' and 'case Q -> C'?

Back

'Case C -> Q' indicates that a characteristic (C) is being studied to see its effect on a question (Q), while 'case Q -> C' suggests that a question (Q) is being used to explore a characteristic (C).

Front

What does a correlation coefficient of .957 indicate?

Back

A correlation coefficient of .957 indicates a very strong positive relationship between the independent and dependent variables, meaning as one increases, the other also tends to increase.

Front

Define 'correlation coefficient'.

Back

A correlation coefficient is a statistical measure that describes the strength and direction of a relationship between two variables.

Front

What is a 'linear relationship'?

Back

A linear relationship is a relationship between two variables that can be graphically represented as a straight line, indicating a constant rate of change.

Front

What is a 'curvilinear relationship'?

Back

A curvilinear relationship is a relationship between two variables that is not linear, meaning the rate of change varies at different levels of the variables.

Front

Explain 'independent variable'.

Back

An independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

Explain 'dependent variable'.

Back

A dependent variable is the variable that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What does 'weak linear' relationship mean?

Back

A weak linear relationship indicates that there is a slight correlation between two variables, but the relationship is not strong enough to predict one variable based on the other.

Front

What is the significance of a 'strong linear' relationship?

Back

A strong linear relationship means that there is a clear and consistent correlation between two variables, allowing for accurate predictions.
