Statistical Analysis Quiz

Why is statistical analysis required?

• To identify trends or patterns in data.

• To create random data sets.

• To eliminate all data errors.

• To ensure data privacy.

During statistical analysis, when would you use a MANOVA?

• When you have one dependent variable and multiple independent variables.

• When you have multiple dependent variables and one independent variable.

• When you have multiple dependent variables and multiple independent variables.

• When you have one dependent variable and one independent variable.

During statistical analysis, when would you use a MANOVA?

• When there is one dependent variable

• When there are 2 or more dependent variables

• When there are no dependent variables

• When there is only one independent variable

Which one of the following is not a characteristic of inferential statistics?

• Hypothesis testing

• Determining relationships

• Presenting data

• Making data inferences

What does the null hypothesis (H0) state in the context of exposure and outcome?

• There is a strong association between the exposure and the outcome.

• There is no association between the exposure of interest and the outcome.

• The exposure causes the outcome.

• The outcome is independent of any exposure.

What does H0 represent in hypothesis testing?

• There is an association between the exposure of interest and the outcome

• There is no association between the exposure of interest and the outcome

• The exposure of interest causes the outcome

• The outcome is independent of any exposure

Why are negative results important in research?

• They confirm the hypothesis without any doubt.

• They provide evidence to prove or disprove a hypothesis.

• They are not useful and should be ignored.

• They always lead to successful experiments.

What is the purpose of obtaining negative results in research?

• To ensure the hypothesis is always correct.

• To alter the hypothesis based on evidence.

• To avoid any changes to the hypothesis.

• To confirm the hypothesis without testing.

What is a P-Value? (Select 2 correct options)

• P < 0.05 is, by convention, an indication of ‘statistical significance’.

• Measures the strength of association

• P > 0.05 is, by convention, an indication of ‘statistical significance’.

• Measures the likelihood that the observed estimate is due to random sampling error
