Mean, Median and Mode are :

answer is d

None of above 

Standard deviation levels.

Mean, Median and Mode are Measure of deviation

The answer would be  D) None of the Above.

To State why not the other three is that 

A)Measures of deviation: Deviation means the Difference between the expected Result from the Actual Result. We can refer to the Regression Line, Where we point to the Actual outputs and Mean and Understand the Deviation to find the Standard Deviation(Changes) by which we can forecast the future output, So these three used the tool to find the Deviation, not the Measure.

B)Ways of Sampling: Mean, Median and Mode consider the whole information. Sampling means taking a smaller portion from the whole and predicting the outcomes. A good example used in Auditing is to give statements on financial Statements or the random sampling Method. So it's not Sampling

C)Measure of Control Tendency: It would be a central Tendency which means it tells us the center most important of the data which helps in decision-making or understanding the data

It's a stastical  measurement  for the calculation 

Sales,total poualtion

measure of central tendency 

Mean,Median and Mode are kinds of measures of central tendency in Statistics

say the list of no.s is 50,60,50,70,20,60,50 ...

here the total no.s is 7, mean would be the average of all which means 360/7 = 51.43; median would be the center no. of the list which is position 4, ans: 70; finally mode will be the value which appears more often in the list, ans: 50 coz it appears 3 times which is more than any other no. in the list

D.none of the above

The answer is d, as mean, median and mode are all measures of central tendency.
