{29, 29, 29, 28, 28, 27}

what is the best measure of center for this data set?

a .mean or median because there is no outlier

b .median because there is an outlier

c .mode because there is an outlier

d. mean because there is an outlier

Option: a is correct.

a .mean or median because there is no outlier

Step-by-step explanation:

Mean and median both try to measure the "central tendency" in a data set.

Clearly from the set of the values or data points:

{29 , 29, 29 , 28, 28, 27}

We could see that the data values are close too each other i.e. there is not outlier ( An outlier is a point that stand out of the rest points i.e. that value is either too high or low as compared to the other data points).

Here we have Mean=28.3333

and Median=28.5

Hence, the correct option is: option: a

a .mean or median because there is no outlier.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
