Total Questions: 100

31. Myer's blended population index is used to measure:

Correct Answer: 4. Digit preference in age data
Solution:

Myer's Blended Population Index is a demographic tool used to measure digit preference or age heaping in reported age data. It helps identify whether respondents disproportionately report ages ending in certain digits (usually 0 or 5). A value of 0 indicates perfectly accurate age reporting, while 100 represents maximum digit preference. It is widely used in censuses to assess data quality.

32. Among the following measures, which one is not included in the Gender Inequality Index (GII)?

Correct Answer: 1. Disparities on the Human Development Index (HDI) by gender
Solution:

The Gender Inequality Index (GII), developed by the United Nations Development Programme (UNDP), measures gender disparities across three key dimensions:
1. Reproductive health (maternal mortality ratio, adolescent birth rate)
2. Empowerment (parliamentary representation, secondary education attainment)
3. Labour market participation
However, disparities on the Human Development Index (HDI) by gender are not included in the GII they are covered separately under the Gender Development Index (GDI).

33. What is the purpose of calculating 'design effect'?

Correct Answer: 2. It is multiplied in sample size calculated to compensate loss of randomization in case of using systematic random sampling.
Solution:

The Design Effect (Deff) is used in survey sampling to account for the loss of efficiency when complex sampling methods (like cluster or systematic sampling) are used instead of simple random sampling.
It is a multiplier applied to the sample size calculated for a simple random sample to adjust for increased variance caused by clustering or systematic patterns in sampling. Hence, it is multiplied with the calculated sample size to compensate for the loss of randomization.

34. In a Life Table, which one of the following formula is used to calculate the probability of dying (ₙqₓ) during the next 'n' years for a person who has reached age х?

Correct Answer: 1.
Solution:

35. Which among the following sampling techniques is based on equal probability?

Correct Answer: 1. Simple Random Sampling
Solution:

Simple Random Sampling (SRS) is the sampling technique based on the principle of equal probability. In SRS, every individual or unit in the population has an equal and independent chance of being selected. It ensures unbiased representation and is the foundation for most probability-based sampling designs.

36. Which one of the following holds true in a normal distribution of data?

Correct Answer: 1. Mean = Median = Mode
Solution:

In a normal distribution, the data are symmetrically distributed around the central value, forming the classic "bell-shaped curve." In this distribution:
• The mean, median, and mode all occur at the same central point.
• The curve is perfectly symmetrical about this mean value.
Thus, the equality Mean = Median = Mode holds true.

37. Which one of the following state has the highest MMR (Maternal Mortality Ratio) for the period 2018-20 as per the SRS Report (November, 2022)?

Correct Answer: 3. Chattisgarh
Solution:

According to the Sample Registration System (SRS) Report 2022, which covers the period 2018-20, the state with the highest Maternal Mortality Ratio (MMR) was Chhattisgarh, recording an MMR of 167 per 100,000 live births. This figure was higher than that of Jharkhand (150), Odisha (147), and Uttarakhand (118).

38. When an instrument gives same reading every time in same condition, it is called:

Correct Answer: 4. Reliable
Solution:

When an instrument gives the same reading consistently under identical conditions, it is said to be reliable. Reliability refers to the consistency or repeatability of measurement results.
• If the results are the same each time under unchanged conditions→the instrument is reliable.
• Accuracy, in contrast, refers to how close the measurement is to the true value.

39. According to 'Registration of Births and Deaths Act 1969', the birth and death respectively, are to be registered within:

Correct Answer: 3. 21 days and 21 days
Solution:

Under the Registration of Births and Deaths Act, 1969, the prescribed time limits are:
• Births: must be registered within 21 days of occurrence.
• Deaths: must be registered within 21 days of occurrence.
These registrations are done at the local registrar's office by the authorized officials.

40. Which of the following calculation takes into consideration both birth and death?

Correct Answer: 2. IMR
Solution:

Among the listed measures:
• TFR (Total Fertility Rate) and GRR (Gross Reproduction Rate) consider only births.
• IMR (Infant Mortality Rate) considers deaths among infants.
• NRR (Net Reproduction Rate) considers both births and deaths, as it measures the number of daughters a woman is expected to bear who survive to reproductive age.
Therefore, NRR takes into account both fertility and mortality.
