Explanation:
The students inserting the zippers are the focus of this study and the reason for the study is to examine the students' sewing skills.
A variable here is the time it takes each student to complete their individual tasks. The independent variables are the number of students, the tools used, and the task, which is the same. The teacher's observation is a quantitative variable as the results are numerical and statistical functions can be applied to them.

The Consumer Price Index (CPI) is a measure of the average change in prices paid by city consumers for a basket of consumer goods and services over time.
Inflation is an increase in the general price level. The official inflation rate is tracked by calculating changes in an indicator called the Consumer Price Index (CPI). CPI tracks changes in the cost of living over time. Like other economic measures, it's doing a pretty good job.
An upward change in the consumer price index (CPI) means that the average price change over time has increased. This ultimately leads to an adjustment of the cost of living and income (presumably so that income can be adjusted for rising costs of living). This process is called indexing.
