Summarizing and Making Inferences from Quantitative Data MCQ

1. Which of the following is appropriate for using the Kendalls tau correlation coefficient?

Two variables measured on nominal scales

Two variables measured on continuous scales

One variable measured on an ordinal scale and one variable measured on a continuous scale

Answer

Correct Answer: One variable measured on an ordinal scale and one variable measured on a continuous scale

Note: This Question is unanswered, help us to find answer for this one

2. Testing an association between two variables requires ______.

Variables measured at least on an ordinal scale

Normally distributed data

Data without measurement error

A true causal relationship between the two variables

Answer

Correct Answer: Variables measured at least on an ordinal scale

Note: This Question is unanswered, help us to find answer for this one

3. Testing for a difference between three groups requires ______.

Normally distributed data within each group

Estimates of a summary measure of location for each group

The assumption that all three groups are different from each other

A true causal relationship between the grouping variable and the dependent variable

Answer

Correct Answer: Estimates of a summary measure of location for each group

Note: This Question is unanswered, help us to find answer for this one

4. Which of the following is TRUE about reference distributions?

There is always a single correct reference distribution for a specific significance test.

The normal distribution is what we should expect data to look like.

Using the right reference distribution means that you do not have to check the quality of your dat

Reference distributions are approximations which may be useful in practice.

Answer

Correct Answer: Reference distributions are approximations which may be useful in practice.

5. In hypothesis testing, a type I error is ______.

Failing to confirm the researchers preferred hypothesis

Missing a real effect

Claiming an effect which is not actually real

Finding an effect which is not consistent with existing literature

Answer

Correct Answer: Claiming an effect which is not actually real

Note: This Question is unanswered, help us to find answer for this one

6. Which of the following is TRUE?

Robust measures are completely unaffected by measurement error.

The median is more robust than the mean.

Using robust measures means that the researcher does not have to worry about the assumptions of statistical methods.

Robust measures are always less efficient.

Answer

Correct Answer: The median is more robust than the mean.

Note: This Question is unanswered, help us to find answer for this one

7. Which of the following is NOT true?

Summary measures of spread capture important features of the whole distribution of data for a variable.

Summary measures of spread are easier to remember than the original dat

Summary measures of spread indicate the amount of variability around a measure of location.

Every data point contributes equally to a summary measure of spread.

Answer

Correct Answer: Every data point contributes equally to a summary measure of spread.

Note: This Question is unanswered, help us to find answer for this one

8. Suppose that one data point in a dataset is altered. Which of the following is guaranteed to change?

Mode

Median

Mean

Mid-mean

Answer

Correct Answer: Mean

Note: This Question is unanswered, help us to find answer for this one

9. Which of the following measures of location is guaranteed NOT to change by adding a single extreme data point?

Mode

Median

Mean

Mid-mean

None of these

Answer

Correct Answer: None of these

Note: This Question is unanswered, help us to find answer for this one

10. Which of the following is NOT true?

Summary measures of location capture important features of the whole distribution of data for a variable.

Summary measures of location are easier to remember than the original dat

Summary measures of location indicate the centre of a set of dat

Every data point contributes equally to a summary measure of location.

Answer

Correct Answer: Every data point contributes equally to a summary measure of location.

Note: This Question is unanswered, help us to find answer for this one
