Graded assigment week 1

My doubt in graded assignment week1 and

 Q -13 &14

Doubt- If all the residents of locality participated in the survey, we can easily infer that if majority of people choose for a lockdown then we should go for a lockdown

And when we ask from only 100 people then we can't be sure whether to lockdown or unlock.

So 13 should be inferential and 14 should be descriptive.

If all the population is participating in the locality then we can perform only descriptive statistics on the data which will be sufficient.

If we are taking a sample of 100  from population(locality) we are making the conclusions of the whole population based on the sample so it is Inferential Statistics

Hello, 

In question 13, all the residents of a locality in Chennai has participated. Assume 1000 residents are living. 1000 is now my population.

Out of these 1000, 590 consider Covid-19 to be a serious disease. 

410 consider it as normal flu and are of the opinion that there should not be any lockdown.

Notice that in the above statements, I am only summarizing the data or facts of survey. No inference about a bigger population is being made. Hence, descriptive.

In question 14, only 100 (sample) out of the possible 1000 (population) residents participated. From this small sample of 100, we are trying to infer what entire 1000 residents feel which may be true or false. (Probability coming into picture). Hence, inferential statistics.
