For each of the following features, say whether it applies to a Spearman correlation:

  • Nonparametric test.

  • Numbers plugged into the formula for the statistic are frequencies.

  • Numbers plugged into the formula for the statistic are ranks.

  • Used if the differences between samples need to be assessed.

  • Used on related data.

  • Uses a statistic called a correlation coefficient.

  • Uses the r statistic.

  • Accept the null hypothesis if the calculated statistic is greater than the critical value of the statistic being looked up in a table.

  • Reject the null hypothesis if P on the SPSS printout is less than 0.05.
