Which value on the number line is the best estimate of the center of the data set? a line plot with fourteen data values. labels are at at twenty-five, thirty, and thirty-five. tick marks are every one unit. values appear as x marks above the line. plot data values are one x mark above twenty-seven, two x marks above twenty-eight, three x marks above twenty-nine, three x marks above thirty, three x marks above thirty-one, zero x marks above thirty-two, one x mark above thirty-three, and one x mark above thirty-four.

I have attached a drawing of the line plot.
Here are the data points from the line plot:


Choosing a measure of central tendency:
Use the mode if there is one number which appears as a vast majority towards the center.
Use the median if there are a lot of outliers. (numbers far away from the rest)
Use the mean otherswise.

In this case, we would use the mean, because there is no number which appears as a vast majority or any outliers.

The mean is calculated by adding up the numbers and dividing by how many numbers you have.

When we add up our numbers, we get 420.
We have 14 numbers.
420 divided by 14 is .
