For the data set {4, 8, 6, 5, 3}, what is the mean?
Steps
Concepts
Step 1: Write down the numbers in the data set: {4, 8, 6, 5, 3}.
Step 2: Add all the numbers together: 4 + 8 + 6 + 5 + 3.
Step 3: Calculate the sum: 4 + 8 = 12, then 12 + 6 = 18, then 18 + 5 = 23, and finally 23 + 3 = 26.
Step 4: Count how many numbers are in the data set. There are 5 numbers.
Step 5: Divide the total sum (26) by the number of numbers (5): 26 / 5.
Step 6: Calculate the division: 26 divided by 5 equals 5.0.
Mean
– The mean is the average of a set of numbers, calculated by summing all the values and dividing by the count of values.
