Question 1:
Answer:
Statistics is the science that deals with the collection, presentation, analysis, and interpretation of numerical data.Question 2:
Statistics is the science that deals with the collection, presentation, analysis, and interpretation of numerical data.Answer:
The fundamental characteristics of data (statistics) are as follows: (i) Numerical facts alone constitute data. (ii) Qualitative characteristics like intelligence and poverty, which cannot be measured numerically, do not form data. (iii) Data are aggregates of facts. A single observation does not form data. (iv) Data collected for a definite purpose may not be suited for another purpose. (v) Data in different experiments are comparable.Question 3:

(ii) Qualitative characteristics like intelligence and poverty, which cannot be measured numerically, do not form data. (iii) Data are aggregates of facts. A single observation does not form data. (iv) Data collected for a definite purpose may not be suited for another purpose. (v) Data in different experiments are comparable.Answer:
Primary data: The data collected by the investigator himself with a definite plan in mind are known as primary data. Secondary data: The data collected by someone other than the investigator is known as secondary data. Primary data are highly reliable and relevant because they are collected by the investigator himself with a definite plan in mind, whereas secondary data are collected with a purpose different from that of the investigator and may not be fully relevant to the investigation.Question 4:
Primary data: The data collected by the investigator himself with a definite plan in mind are known as primary data. Secondary data: The data collected by someone other than the investigator are known as secondary data. Primary data are highly reliable and relevant because they are collected by the investigator himself with a definite plan in mind, whereas secondary data are collected with a purpose different from that of the investigator and may not be fully relevant to the investigation.Answer:
(i) Variate: Any character that is capable of taking several different values is called a variant or a variable. (ii) Class interval: Each group into which the raw data is condensed is called a class interval. (iii) Class size: The difference between the true upper limit and the true lower limit of a class is called its class size. (iv) Class mark of a class: The class mark is given by Upper limit+Lower limit2. (v) Class limit: Each class is bounded by two figures, which are called class limits. (vi) True class limits: In the exclusive form, the upper and lower limits of a class are respectively known as true upper limit and true lower limit. In the inclusive form of frequency distribution, the true lower limit of a class is obtained by subtracting 0.5 from the lower limit, and the true upper limit of the class is obtained by adding 0.5 to the upper limit. (vii) Frequency of a class: The frequency of a class is the number of times an observation occurs in that class. (viii) Cumulative frequency of a class: Cumulative frequency of a class is the total of all the frequencies up to and including that class.
Answer:
Range = Maximum value - minimum value = 100 - 46 = 54 Thus, the range is 54.Question 19:
Range = Maximum value - minimum value
= 100 - 46 = 54
Thus, the range is 54.
Answer:
(i) class mark=upper limit+lower limit2=120+902=2102=105 (ii) mid-value = 10 width = 6 Let the lower limit of the class be x . upper limit = x + 6 class mark/mid-value=upper limit+lower limit2 (iii) width = 5 lower class limit of lowest class = 10 The classes will be 10-15, 15-20, 20-25, 25-30, 30-35. The upper class limit of the highest class = 35. (iv) Class marks = 15, 20, 25, ... class size = 20 - 15 = 5 Let the lower limit of class be x . Thus, the class is 17.5-22.5. (v) 20 will be included in the class interval 20-30.
Question 2:
(d) 26 We have: Maximum value = 32 Minimum value = 6 We know: Range = Maximum value - Minimum value =32 - 6 =26Answer:
(b) 110 Classmark = Upper limit+Lower limit2=120+1002=110Question 3:
(b) 110 Classmark = Upper limit+Lower limit2=120+1002=110Answer:
(b) 20−30 This is the continuous form of frequency distribution. Here, the upper limit of each class is excluded, while the lower limit is included. So, the number 20 is included in the class interval 20−30.Question 4:
(b) 20−30 This is the continuous form of frequency distribution. Here, the upper limit of each class is excluded, while the lower limit is included. So, the number 20 is included in the class interval 20−30. Answer:
(b) 17.5-22.5
We are given frequency distribution 15, 20, 25, 30,...
Class size = 20 - 15 = 5
Classmarks = 20
Now,
Lower limit=20-52=352=17.5Upper limit =20+52=452=22.5
Thus, the required class is 17.5-22.5.
