What is the mean of the set?

If an additional dot is added to the set in the 3 column, how will the mean change? What will the new mean be?

Answer 1

Answer:

The mean will change because the total number of dot will increase and a bigger mean than the previous will occur. The new mean is 4. The old mean is 3.75.

Step-by-step explanation:

Answer 2

The old mean is 3.2 and the new mean is 3.8. Then there is an increment in the mean.

What is Mean?

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency. Arithmetic mean is a term used to describe the average. It's the percentage of the actual number of observations to the sum of the observations.

The dot plot is shown.

Then the mean will be

Mean = (2 + 2 + 3 + 9 + 0)/5

Mean = 16/5

Mean = 3.2

If an additional dot is added to the set in the 3 columns.

Then the new mean will be

New mean = (2 + 2 + 3 + 9 + 3)/5

New mean = 19/5

New mean = 3.8

Then the mean will increase.
