A researcher wants to examine the relation between class rank and popularity among peers.Class rank is provided by the school and includes each student's rank in order.The researcher assesses popularity using a likability measure that provides scale data.What does the researcher need to do to the data before calculating a statistic using a nonparametric test?
A) compute difference scores
B) convert the scale data to ordinal data
C) subtract the mean from each score
D) standardize the scores

Since class rank is already provided in ordinal data, the likability measure needs to be converted to ordinal data as well in order to use a nonparametric test. Therefore, the researcher needs to assign numerical ranks to each likability score, creating an ordinal variable. The other options (compute difference scores, subtract the mean from each score, standardize the scores) are not relevant to converting likability data to ordinal data.
