- A. Median
- B. Mean
- C. Mode
- D. Geometric Mean
- E. Harmonic Mean
Explanation: The mode is the value occurring most frequently in a data set. The median is the middle value and the mean is an arithmetic average, so…
Correct answer: Mode- A. Arithmetic Mean
- B. Harmonic Mean
- C. Geometric Mean
- D. Mode
- E. Median
Explanation: The ordinary geometric mean is defined for positive observations because it is based on products and equivalent logarithms.
Correct answer: Geometric Mean- A. Not
- B. Highly
- C. Less
- D. None of these
Explanation: Arithmetic mean uses every value, so an unusually large or small observation pulls the mean toward itself.
Correct answer: Highly- A. Median
- B. Harmonic Mean
- C. Mean
- D. Mode
- E. None of these
Explanation: The arithmetic mean is obtained by adding all observations and dividing their sum by the number of observations.
Correct answer: Mean- A. Mean
- B. Variance
- C. Geometric Mean
- D. Median
- E. Mode
Explanation: Variance measures the average of squared deviations from the arithmetic mean, so the mean is the reference point in its calculation.
Correct answer: Mean- A. Mean
- B. Mode
- C. Median
- D. Variance
Explanation: The sum of squared deviations is minimized when deviations are measured from the arithmetic mean.
Correct answer: Mean- A. All People living in a country
- B. All People living in the are under study
- C. All subjects or objects whose characteristics are being studied
- D. None of the above
Explanation: A population is the complete set of subjects or objects whose characteristics are being investigated.
Correct answer: All subjects or objects whose characteristics are being studied- A. variable
- B. Constant
- C. Discrete variable
- D. Continuous variable
Explanation: Road accidents are counted in whole numbers such as 0, 1, or 2, so their number is a discrete variable.
Correct answer: Discrete variable- A. Constant
- B. Variable
- C. Quantitative data
- D. Qualitative data
Explanation: Traditional statistical methods are mainly designed for quantitative data, so statistics has difficulty handling purely qualitative…
Correct answer: Qualitative data- A. variable
- B. Constant
- C. Primary data
- D. Secondary data
Explanation: When a Patwari directly collects information about cotton crops for the purpose of the study, the information is primary data.
Correct answer: Primary data- A. Official data
- B. un-official data
- C. Primary data
- D. Secondary data
Explanation: NADRA collects applicants' information directly while issuing identity cards, so it is primary data for that collection process.
Correct answer: Primary data- A. Primary source
- B. secondary source
- C. Organized data
- D. none
Explanation: When census reports are used by someone as an existing source, they are secondary data because the user did not collect them firsthand for…
Correct answer: secondary source- A. Has no role
- B. Average
- C. Plays an Important role
- D. Study
Explanation: Statistics plays an important role in natural sciences by summarizing observations, quantifying variation, and helping researchers draw…
Correct answer: Plays an Important role- A. Other sciences
- B. physics
- C. Business
- D. Literary subjects
Explanation: Statistics helps test and verify laws or relationships proposed in other sciences by comparing them with observed numerical data.
Correct answer: Other sciences- A. Useless
- B. Various Methods
- C. Unavoidable
- D. Samples
Explanation: Planning depends on data about current conditions, trends, resources, and likely outcomes, so statistical use is unavoidable.
Correct answer: Unavoidable- A. Economics
- B. Mathematics
- C. Research
- D. Computer
Explanation: Research relies on statistics to collect, organise, analyse, and interpret evidence, which is why statistics is commonly called its…
Correct answer: Research- A. Singular Sense
- B. Plural Sense
- C. Singular as well as plural sense
- D. Non of these
Explanation: “Statistics” has a plural sense when it means numerical facts, and a singular sense when it means the discipline or method of analysing…
Correct answer: Singular as well as plural sense- A. Descriptive
- B. Ability
- C. Qualitatively
- D. Quantitatively
Explanation: Statistics deals with numerical facts, so statistical information is expressed quantitatively.
Correct answer: Quantitatively
