ab: Summary: Correlation is a basic statistical concept which is necessary for
understanding the relationship between two variables when they change
values. In the secondary curriculum of Korea, only in formal definition
of correlation is taught with two-way data representations such as
scatter plots and contingency tables in the middle school. In this
study, we investigated Korean high school studentsâ€™ understanding of
correlation using a test consisting of 35 items about interpretation of
scatter plot, contingency table, and text in realistic situation. Two
hundred and sixteen students from a high school in Seoul took the test
for 20 min. Most of students could tell a correlation and the direction
of the correlation between two variables presented in a scatter plot.
However, they exhibited the confusion between the steepness of slope
and the strength of the correlation. Students had difficulties in
determining the amount of association between two qualitative variables
when the data are given in a 2-by-2 contingency table.
