Please briefly explain why you feel this answer should be reported.
We use the mean formula to find the mean of 4, 8, 15, 16, 23, and 42.
Mean = Sum of all observations/Number of observations.
We follow the below steps to find the mean of 4, 8, 15, 16, 23, 42.
Step 1: Write the given data as 4, 8, 15, 16, 23, 42.
Step 2: Add all the values of the dataset: 4 + 8 + 15 + 16 + 23 + 42 = 108.
Step 3: Count the number of values or elements in the given dataset.
There are 6 values or numbers in the dataset.
Step 4: Write the formula
Mean = Sum of all observations/Number of observations.
Step 5: Substitute the values of step 2 and step 3 in the formula
Mean = 108/6 = 18.
So, the mean of dataset [4, 8, 15, 16, 23, 42] is 18.
