RMH Exam Study

1. Which of the following is a parametric test?

Chi-Square Test

Unpaired t Test

Mann Whitney U Test

2. What is alpha?

A pre-set probability which Ho is either accepted or rejected

The sample size deviation

The sample size

The standard error of the mean

3. What are population parameters?

The scores of one group are not correlated or related to the scores of any other group

Represents statistics describing the actual state of the population

The extent to which a test generates correct statistical decisions even when the assumptions have been violated

4. When we are dealing with a single group or sample we use the

Unpaired t Test

One Sample t Test

Chi-Square Test

Mann Whitney U Test

5. What is sampling error?

A bath tub full of black and white marbles

The discrepancy between the sample statistic and the actual population parameters

The collection of relevant evidence

Rejecting the null hypothesis when in fact it is still valid

6. The degree of freedom equation changes depending on whether your using a parametric or non-parametric test. True or false?

True

False

7. Which of the following is not an assumption of a parametric test?

Equal sample sizes between two groups

High 'n' values

Equal or similar variance values

Data must be presented in a table

8. A parametric test is used for

Interval data

Nominal data

Ratio data

Ordinal data

Submit

9. If t-obtained is more then t-critical

Null hypothesis should be accepted

Null hypothesis should be rejected

10. What is a confidence interval?

A percentage of assurance that the mean is accurate

A range of values which will contain a true population parameter

A percentage of assurance that the standard deviation is accurate

A range of values excluding the true population paramater

11. A test is called 'robust'.
What does this refer to?

The scores of one group are not correlated or related to the scores of any other group

Represents statistics describing the actual state of the population

The extent to which a test generates correct statistical decisions even when the assumptions have been violated

12. What is inferential data analysis?

The frequency distribution of a sample means drawn from a population

The exact probabilities for obtaining a sampling outcome for a specified population

The way in which we use sample data for testing hypotheses concerning populations

The process of looking for hidden meaning underpinning the discourses implicit meaning

13. The Unpaired t test

Calculates the value of the statistic for the difference between the two observed mean groups

Asks if the two variables that are used to characterise populations are independent

States that there is no true difference between two groups, but rather differing is due to a sampling error

14. Non parametric tests are used for

Interval data

Nominal data

Ratio data

Ordinal data

Submit

15. True or false
You reject the null hypothesis if the computed value of x2(Chi-squared) is less than or equal to the critical value of x2 for the chosen alpha level

True

False

16.
The Chi-Square Test

Calculates the value of the statistic for the difference between the two observed mean groups

Asks if the two variables that are used to characterise populations are independent

States that there is no true difference between two groups, but rather differing is due to a sampling error

17. Which of the following is a non-parametric test?

Chi-Square Test

Unpaired t Test

Mann Whitney U test

Submit

18. Binomial theorem can be best used for calculating sampling distributions for what scale of data?

Ratio

Interval

Ordinal

Nominal
