Question

All the statements are correct EXCEPT;

 A) Samples are limited groups of subjects selected for study from larger target populations.

 B) Sample data is used to make inference about the population.

 C) Population is a limited group of subjects selected for study from a larger sample.

 D) Simpson's paradox is a phenomenon where a trend appears in several different groups of data but disappears or reverses when these groups are combined.

 E) We are not allowed to change the result we found from a study to achieve our goals. 

Answer 1

Option C is incorrect.

Reason:  In statistics, population refers to the total set of observations that can be made.Population is the entire pool from which a statistical sample is drawn.

So we select sample from the population to study about population characteristics. We can never select population from a sample.

Answer 2

Answer 3

In statistics and quantitative research methodology, a data sample is a set of data collected and the world selected from a statistical population by a defined procedure.

The elements of a sample are known as sample points, sampling units or observations.

Typically, the population is very large, making a census or a complete enumeration of all the values in the population either impractical or impossible. the sample usually represents a subset of manageable size.

Samples are collected and statistics are calculated from the samples, so that one can make inferences or extrapolations from the sample to the population.

Simpson's paradox is a phenomenon in probability and statistics, in which a trend appears in several different groups of data but disappears or reverses when these groups are combined.

We are not allowed to change the result we found from a study to achieve our goal.

Hence, the incorrect statement and thus the answer is:

(C)

Answer 4

ANSWER :

A. Correct. Samples are selected from a population.

B. Correct. Samples are selected from a population to study the population characterises.

C. Incorrect. Samples are part of population under study.

D. Correct. This is the outcome of experiments done by Simpson.

E. Correct. How one can change the result which is outcome of a study to achieve goals. If it is done then goals will not be achieved.

So, Option C is the incorrect statement ( (ANSWER).
