## Step 1The problem is asking us to identify the variable of interest in a survey conducted to determine the popularity rating of the current president. The variable of interest is the aspect of the study that we are interested in observing.## Step 2In this case, the variable of interest is "The president's job performance". This is because the survey is designed to gauge the public's perception of the president's job performance.## Step 3Next, we need to determine whether this variable is quantitative or qualitative. A quantitative variable is one that can be measured on a numerical scale, while a qualitative variable is one that cannot be measured on a numerical scale.## Step 4The variable "The president's job performance" is a qualitative variable because it is based on people's opinions and perceptions, which cannot be measured on a numerical scale. People's opinions about the president's job performance can vary greatly and are not based on a numerical scale.
