Statistics 101 - The larger a sample size, the more legitimacy your data has

[ck4829]

Having a poll or survey that asks a question to 14 people has less credibility than a poll or survey that asks that question to 100 people and that in turn has less credibility than a poll or survey that asks that same question to 10,000 people.

Just a little something to remember... legitimacy, credibility... when Republicans want a "red wave" this year and in 2024 when everyone is not able to vote. Do we have an appropriate sample size?

1. Generally true as long as the sample is truly RANDOM. Sample size determines the POWER

of the study--i.e., the ability of the study to identify statistically-significant differences and correlations where they exist. However., a non-random sample--one which introduces sampling bias--is not more valid no matter the size.

2. Provided the sample is random. nt

3. I took Statistics for Social Science.

I was told if you have one antidote, you have data.

4. All other things being equal, and when is that the case?

Statistics 102 - Statistics is complex. Sampling, inferential statistics, always has error compared to descriptive statistics, polling everyone instead of sampling. So, given sampling, you don't know if what you said is true or not, just that is is statistically more probable, in other words using "credibility" is correct and certainty would not be.

In political polling, objectivity, independence, lack of bias, and ability to correctly sample are huge factors, and there are a lot of bad actors producing skewed polling to sway public opinion by purposefully designing polls to reflect desired results, a very easy thing to do. That, and bad actors such as #FailedCoupGuy (double entendre intended) just pay people to lie about polls.

5. Statistics was a hoot, I think I got a C grade

and I put in some effort. Your right, ask 3 people how they like Joe and if 2 don't like him = 33& approval rating. Ask 100 people and he might be 60% approval. I am not seeing a red wave again ever. The Blue builds.
