    Ans: Stem and leaf Display is a statistical technique to present a set of data.
12. What is frequency polygon?
    Ans: A frequency polygon expresses distribution of data by meab of a single line determined by the midpoints of classes.
13. what is pie chart?
    Ans: A pie chart presents the data in the form of a circle.
14. what is data?Ans: A collection of any number of related observations of none or more variables are called data.
15. what is raw data?Ans: Information before it is arranged or analyzed by statistical methods are raw data.
16. What is classification?Ans: classification is the process of arranging data as collected by proper investigation in some groups or class in relation with definite. characteristics grouping of related facts into classes.
17. what is bar diagram?Ans: Bar diagrams are the most common type of diagrams used in practice. A bar is a thick line whose width is shown merely for attention.
18. what is Scatter diagram?
    Ans: A graph of points on a rectangular grid the X and Y coordinates of each point corresponded to the two measurements made on some particular sample element and the pattern of points illustrates the relationship between the two variables.
19. What is Sample?Ans: A collection of some but not all of the elements of the population under study used to describe the population.
20. What is data array?Ans: An organized display of data that shows the number of observations from the data set that falls into each of a set of mutually exclusive and collectively exhaustive classes is frequency distribution.
21. What is frequency density?Ans: frequency density is the percentage of observation fall within each class in respect of their class width.
22. what is population?Ans: A collection of all the elements we are studying and about which we are trying to draw exclusions.
23. what is central tendency?Ans: Central tendency is a typical value of a data set around which other figures congregate.
