Spearman's Correlation Coefficient & scatter graphs/LoBF

If you have 2 values tied for the 6th and the 7th place, then what rank do you put for both of them?

• 6

• 7

• 6.5

• It depends on the actual values for the 6th and 7th ranked data pieces.

Which is a reason we would not use Spearman's Rank Correlation Coefficient?

• Data follows a linear trend

• Data follows a non-linear trend

• There are data points not necessarily in line with the rest of the data but they are still not outliers

• The r_p is not showing a strong correlation for a given set of data

What does Spearman's Correlation Coefficient tell us?

• How strong the correlation between the data is

• A line of best fit for the data

• How strong an upward or downward trend the data has

• If the correlation between our variables is linear or non-linear
