Measures of central tendency are called such because

a.
they all find a different "center" of a data set.
b.
they all find approximately the same "center" of a data set.
c.
they are all different ways to find the exact same "center" of a data set.
d.
they all find a different type of "center" of a data set, which may or may not be the same value.

Answer with explanation:

The three Measures of central tendency are

1. Mean

2. Median

3. Mode

→If the data set is Symmetrical, then at the center

Mean =Median =Mode

And, mean is best suited to evaluate for this kind of  Data set to calculate center.

→If the data set is skewed, Median is best way to calculate center.

→For, categorical data set, like, shoe size worn in a country, Mode is perfect way  to read this kind of data set.

So,from above three statement we can conclude that, the three that is , Mean , Median, and Mode may vary or same for a Data set.

Option D, looks most Appropriate.

  They all find a different type of "center" of a data set, which may or may not be the same value.
