Sampling A1

[dipachatterjee]

What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

Completing the Sampling assignment with one edit to the code.

What did you learn from the changes you have made?

I learnt how to identify sample type, population, distribution, and how to determine what a code might mean in reference to sampling.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

I followed the assignment's instructions and completed the assignment in VSCode using python packages.

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

The major challenge was understanding the code. I haven't coded before, and we didn't go over how sampling would look like as a code (practical). So that was a major challenge. Otherwise, just needed to read up on sampling.

How were these changes tested?

The simulation was run with the code block.

Good.

Some discrepancies found:
Q1:
Stage 1: Distribution is not binomial. It is uniform random selection without replacement, which is equivalent to hypergeometric.
Stage 2: “Sampling with replacement” is incorrect. Each infected person undergoes one independent Bernoulli trial.

Q2: Your intuition in the last sentence the standard error/noise decreases exponentially (sorry I'm not explaining this well). is right. You probably want to say that the noise decreases with the number of repetitions, consistent with the Law of large numbers (not exponentially)

Well done!
