221. Continuous variable can assume __________ value?
- A. All possible
- B. Constant
- C. Accuracy
- D. Specific
Explanation: A continuous variable can take any value within an interval, including fractional values such as 2.4 or 2. forty-one, subject to measurement precision. Thus it is not restricted to specific or constant values.
Correct answer: All possible222. Usually measurements give rise to ________ data?
- A. Discrete
- B. Specific
- C. Continuous
- D. Constant
Explanation: Measurements such as height, weight and time can vary by arbitrarily small amounts, so they generally produce continuous data. Discrete data usually result from counting whole units.
Correct answer: Continuous223. Data being used by an agency which is originally collected by them are _______ data?
- A. Quantitative
- B. Primary
- C. Discrete
- D. Secondary
Explanation: Data collected originally by the agency that uses them are primary data. Secondary data are obtained from another person's or organisation's prior collection.
Correct answer: Primary224. Statistics laws are true for______________?
- A. Short run
- B. Long run
- C. Medium period
- D. None of these
Explanation: Statistical laws describe regularities that emerge from a large number of observations, not necessarily from one short series. Therefore they are regarded as valid in the long run.
Correct answer: Long run225. Statistical Laws are valid in the ________________?
- A. Long run
- B. Plural sense
- C. indefinite
- D. Short run
Explanation: Statistical regularities become dependable when repeated observations are considered over a long period or large number of trials. Short-run results may show substantial random variation.
Correct answer: Long run226. A characteristics that does not change is called______________?
- A. variable
- B. Attribute
- C. Constant
- D. None of these
Explanation: A characteristic that remains fixed and does not vary is called a constant. A variable, by contrast, can take different values among observations.
Correct answer: Constant227. _________ used the word statistics for the first time during one of his lectures at a German university?

- A. Inferential

Correct answer: Descriptive229. Most of the recent developments in statistics arose to meet the needs of ____________?
- A. Biology
- B. Three reasons
- C. Hands
- D. Physics
Explanation: Many modern statistical techniques developed in response to practical problems in biology, especially variation, heredity, and population studies. Among the given options, biology is the relevant field.
Correct answer: Biology230. Statistics Laws are true________________?
- A. In each case
- B. Average
- C. Facts
- D. Field
Explanation: Statistical laws usually describe regularities for groups and are therefore true on average, not necessarily for every individual case. This distinguishes them from exact universal laws.
Correct answer: Average
