To determine the average daily hours of screen use for PGCC (Prince George's Community College) students aged 18-29, you would typically calculate the **mean**, which is the average of the data set. However, you might also consider the **median**, **mode**, and **range** to provide a fuller picture of the data. Here's what each term means in this context:
1. **Mean**: The sum of all the daily screen use hours divided by the number of students surveyed. This provides the average screen time.
2. **Median**: The middle value when all daily screen use hours are arranged in ascending order. This is useful for understanding the central tendency, especially if there are extreme values (outliers) that could skew the mean.
3. **Mode**: The value that appears most frequently in the daily screen use hours. This can provide insight into the most common screen use duration among the students.
4. **Range**: The difference between the maximum and minimum values in the data set. This provides information about the variability in screen use among students.
To calculate these values, you would need to collect data on the daily screen hours from a sample of PGCC students within the specified age range. Once you have the data, you can compute each of these statistics to better understand screen use habits in this demographic. If you already have the data, I can help guide you through the calculations!
