  • 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
