Answer:
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.
