10. A Statistic:

zt is a descriptive measure computed from the data of a POPULATION ,GROWTH.PROGRESS NON OF THESE

( sample)

11. A Parameter:

It is a a descriptive measure computed from the data of . a population ,SAMPLE, GROWTH

12. A measure of central tendency is a measure which indicates where the of the data is. Middle,UPPER LOWER
13. The three most commonly used measures of central tendency are:

The Mean, the Median, and MADE,MUDE, the Mode.

14. Here is a random sample of size 10 of ages, where

= (42 + 28 + … + 37) / 10 = 36.2,36.3,36.4,36.5,36.6

15. (n+1)/2 th IS THE FORMULA OF

MEAN MOD OR MEDIAN

16. If all values are different there is no

MEAN ,MEDIAN MODE

17. Sometimes, there are more than one
18. MEAN ,MEDIAN MODE
19. A descriptive value for a population is called

SAMPLE POPULATION PARAMETER

19. Quantitative Variable S S S

20. The Mean and Median are Special cases of a family of parameters known as ………………? location parameters. ,location sample, lacation technique
21. Other location parameters which help us to determine the position of a particular observations in a data are called Measures of

position.,sample,population

22. These Measures of Position when help us to divide the sample data into n equal parts, or divide the probability distribution into contiguous interval with equal probabilities are called QUINTILES.quartiles,quality,quantity

Q23. cut points are a lso called………..?

Mode median mean quantiles

24. quantiles denoted by

Q Q Q k F S

25) is defined as the extent to which the observations in the dataset are spread away from the central value.
