Step 1

We do this by adding the number of students in each age group for each year. For 1980, the total number of students is $7282 + 7129 + 3788 = 18199$. For 1985, the total number of students is $7362 + 6654 + 3716 = 17732$. For 1990, the total number of students Show more…

Key Concepts

Data Aggregation

This concept involves collecting individual data points from a table and combining them, usually through summing, to form aggregate values. This process is essential for reducing complex data sets into more straightforward totals or summaries that can then be more easily compared or analyzed.

Temporal Comparison

This concept pertains to analyzing changes over different time periods. It involves comparing aggregated data from sequential intervals to identify trends, such as an increase or decrease in values over time.

Trend Analysis

Trend analysis is the process of looking at data collected over time to determine patterns, such as consistent increases or decreases. It involves not only comparing totals for each period but also interpreting these changes to understand broader dynamics within the datasets.
