The Correct Answer and Explanation is :
Step-by-Step Explanation:
1. Average (Mean):
The average is calculated by summing all the values in a dataset and dividing by the number of data points.
- For Hours Online: Add all the hours online/week, then divide by the total number of students.
- For Number of Friends: Add all the friends’ numbers, then divide by the total number of students.
2. Median:
The median is the middle value when the data points are arranged in ascending order. If there is an even number of data points, it is the average of the two middle values.
- For Hours Online: Order the values and find the middle one (or the average of the two middle ones).
- For Number of Friends: Similarly, arrange the number of friends and find the middle value.
3. Midrange:
The midrange is calculated as the average of the maximum and minimum values in the dataset.
- For Hours Online: Take the maximum and minimum values of hours online/week, then calculate their average.
- For Number of Friends: Similarly, calculate the midrange by averaging the maximum and minimum values of friends.
4. Mode:
The mode is the value that occurs most frequently in a dataset.
- For Hours Online: Identify the most frequent number of hours online/week.
- For Number of Friends: Identify the number of friends that occurs most frequently.
Application of Formulas:
Let’s break down the steps using the data provided. However, I cannot directly perform the calculations without further details or access to the file. You can input these values into Excel as follows:
- For the Average: Use the
=AVERAGE(range)function. - For the Median: Use the
=MEDIAN(range)function. - For the Midrange: Use the formula
(MAX(range) + MIN(range))/2. - For the Mode: Use the
=MODE(range)function.
Once you perform these calculations, you will compare the results:
- Compare the measures of location (average, median, midrange, mode) to see how they differ or align, which can give insights into the distribution of the data.
