Question

In a statistics class, the statistics lecturer noticed that many students were surfing Facebook more often than they were studying the statistics assignments that the lecturer had set for them. He wanted to see the impact that this behaviour on their examination performance. He therefore collected data from 260 students of his course. He classified each students as either someone who had log in Facebook during their lab class or someone who never did. After the statistics exam, he classified the students into those who had passed or failed the exam. A test was conducted to determine whether there was a relationship between these two variables.

b. State the variables involved and the measurement of the variables (continuous / categorical)

Answer 1

Answer (b)

There are two variables involved in this test, one is facebook use and other is exam result

Data is collected for 260 students, but variables have categorical measurement.

Facebook use has two categories, i.e. someone who had log in Facebook during their lab class or someone who never did and exam result has two categories, i.e. pass or fail.

So, measurement of variables is categorical for both variables as there is no numerical value involved in both variables.
