3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6. Which term best describes this value: average, mean, median, mode, or standard deviation
Average and mean are the same thing. So the best term to describe it is average or mean, either is good.
Lilly is right.
To determine which term best describes the value obtained, let's first understand what each term means:
1. Average: The average is the sum of all values divided by the number of values. It is calculated by adding up all the values and then dividing by the total count.
2. Mean: The mean is another word for average. It represents the central tendency of a set of values and is calculated by summing up all the values and dividing by the total count.
3. Median: The median represents the middle value in a sorted set of values. It is the value that falls exactly in the middle when the values are arranged in ascending or descending order. If there is an even number of values, the median is the average of the two middle values.
4. Mode: The mode is the value(s) that appear most frequently in a set of values. There can be multiple modes or no mode at all if no value is repeated.
5. Standard Deviation: The standard deviation measures the amount of dispersion or variability in a set of values. It quantifies how spread out the values are from the mean.
In this case, we are given a set of values: 3, 5, 8, 12, and 20. By adding them up and dividing by the number of values (5), we obtain an average of 9.6. Therefore, the term that best describes this value is "average" or "mean."
