SP6-SpearmanRank

The Pearson correlation coefficient is used for linear relationships only.

• True

• False

Spearman's rank correlation is more sensitive to outliers compared to Pearson's correlation.

• True

• False

When should you use Spearman's rank correlation instead of Pearson's?

• When data has no trend

• When data is nonlinear

• When data is random

• When data is linear

What is the first step in calculating Pearson's correlation using a calculator?

• Calculate the mean

• Turn on the calculator

• Enter data into lists

• Draw a scatter plot

What should you do if your calculator does not show the R value after running a linear regression?

• Change the batteries

• Re-enter the data

• Turn on the Stats diagnostic mode

• Restart the calculator

How do you handle ties when ranking data for Spearman's correlation?

• Ignore the ties

• Assign random ranks

• Assign the same rank to tied values

• Average the ranks of tied values

Why can't Pearson's correlation be used when one variable is already ranked?

• Pearson's is only for categorical data

• Pearson's is only for numerical data

• Pearson's requires both variables to be continuous

• Pearson's is not suitable for ranked data
