(A) Cohort Study (B) Cross Sectional Study (C) Natural Experiment Study (D) Clinical Trial
Check Answer
Answer: Natural Experiment Study.
Explanation: John Snow’s investigation of the 1854 cholera outbreak in London is considered a classic example of a natural experiment study where the exposure to contaminated water acted as a natural intervention.
Q-3 A person found correlation between fatty food intake and a disease due to obesity, Heldid this by collecting data from the food manufacturers & hospital respectively. Such a study is – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A) Ecological Study (B) Cross Sectional Disease (C) Psephological Study (D) Experimental Study
Check Answer
Answer: Ecological Study.
Explanation: Ecological studies analyze data at the population level, often using existing data sources like food manufacturers and hospitals to explore associations between variables without individual-level data.
Q-4 Which is not a analytical study – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A) Case Control (B) Cohort Study (C) RCT (D) Cross Sectional
Check Answer
Answer: RCT (Randomized Controlled Trial).
Explanation: Randomized Controlled Trials are experimental studies, not analytical ones. Analytical studies include observational designs like case-control and cohort studies.
Q-5 In a study in UK, an association was found between sale of antiarrythmic drug and an increase in deaths due to asthma. This is an example of. – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)Ecological Study (B)Cohort Study (C)Case Reference Study (D)Experimental Study
Check Answer
Answer: Ecological Study.
Explanation: This scenario describes an ecological study where associations are made at the group level without individual-level data, often leading to hypotheses for further investigation.
Q-6 What is not true about cross sectional study? – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)It is a Prevalence Study (B)Tells Etiology (C)Shows Pattern of Disease (D)Tells Prevalance
Check Answer
Answer: Tells Etiology.
Explanation: Cross-sectional studies provide a snapshot of a population at a single point in time, focusing on prevalence rather than causation or etiology.
Q-7 True about case control study is: – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)Not Possible For Rare Disease (B)Odds Ratio Cannot be calculated (C)Attributable Risk Cannot be calculated (D)Bias is not Seen
Check Answer
Answer: Bias is not Seen.
Explanation: Case-control studies are susceptible to bias, including selection and recall bias, which researchers must address to ensure the validity of their findings.
Q-8 Regarding case control study true is – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)Useful for rare diseases (B)Incidence can be calculated (C)Takes longer time (D)Relative Risk can be calculated
Check Answer
Answer: Useful for rare diseases.
Explanation: Case-control studies are particularly useful for investigating rare diseases or outcomes where cohort studies may be impractical due to the need for large sample sizes.
Q-9 Which of the following is true about cohort study – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)Disease to risk factor study (B)Effect to cause study (C)Not associated with Attributable Risk (D)Associated with Antecedent causation
Check Answer
Answer: Disease to risk factor study.
Explanation: Cohort studies follow individuals over time to assess how exposure to risk factors influences the development of diseases, focusing on establishing causal relationships.
Q-10 20 Pregnant women were asked about about the history of smoking when they came for regular antenatal visit and then followed up to see how many of them had low birth weight babies, What is the type of study? – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
Explanation: This scenario describes a prospective cohort study where participants are followed over time from exposure to outcome, allowing researchers to assess causal relationships.
Q-11 Natural history of disease is studied with – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
Explanation: Longitudinal studies track individuals over time to observe the progression of diseases or conditions, providing insights into natural history and outcomes.
Q-12 What type of data is obtained from existing records and data sources such as medical records? – (Telegram Channel par sab milega ➡ @ayurveda_sidhi)
(A)Primary Data (B)Seconday Data (C)Tertiary Data (D)Qtertiary Data
Check Answer
Answer: Secondary Data.
Explanation: Secondary data refers to information collected by others for purposes other than the current research, such as medical records or databases that researchers analyze for their studies.
Q-13 Selection bias can be eliminated by – (uploaded by Ayurvedasidhi.com)
Explanation: Randomization helps distribute potential confounders evenly among groups, reducing selection bias and strengthening the internal validity of a study.
Q-14 Bias can be eliminated by all except: – (uploaded by Ayurvedasidhi.com)
Explanation: Multivariate analysis is a statistical method used to explore relationships between multiple variables but does not directly eliminate bias; techniques like randomization and blinding help mitigate bias in research studies.
Q-15 Which is classical form of research – (uploaded by Ayurvedasidhi.com)
(A)Case control study (B)Cohort Study (C) Experimental Study (D) Cross-Sectional Study
Check Answer
Answer: Experimental Study.
Explanation: Experimental studies involve manipulating variables to observe their effects on outcomes, representing a classic approach in scientific research for establishing causal relationships.
Q-16 Confounding means – (uploaded by Ayurvedasidhi.com)
(A)Measure Error (B)Reporting Error (C)Real But Misleading (D)Investigator Error
Check Answer
Answer: Real But Misleading Explanation: Confounding occurs when an external factor influences both the dependent variable and independent variable, leading to misleading conclusions if not properly addressed in research design or analysis.
Q-17 Recall bias is most commonly associated with – (uploaded by Ayurvedasidhi.com)
(A)Case control study (B)Cohort Study (C)Cross sectional study (D)RCT
Check Answer
Answer: Case control study Explanation: Recall bias can occur in case-control studies when participants’ ability to accurately recall past exposures or events is influenced by their disease status, potentially leading to distorted results.
Q-18 which of the following is not systematic error – (uploaded by Ayurvedasidhi.com)
Answer: Measuring Error Explanation: Measuring error refers to inaccuracies in data collection or measurement processes but does not fall under systematic errors like confounding, selection bias, or information bias.
