In Ontario, they have gone from 17,605 people tested on Sept. 9th to December when the daily number of tests have grown exponentially to over 68,000 per day.
Increasing the sample size only further validated that the portion of the population affected has NOT changed.
...and at a great expense!
COVID-19 and Prevalence Made Easy:
If I told you that there were 10,000 people in one town - and that I gave only 10% of them $1, and...
- If you asked 10 and only 1 said "yes" - you would rightly be skeptical.
- If you asked 100 and 10 said "yes" - you would likely admit that the 10% was starting to look more plausible.
- If you asked 1000 and and 100 said "yes" - you would probably be more convinced.
- If you asked all 10,000 and exactly 1000 said "yes" - you would have confirmation.
By increasing the sample size, you only confirmed the % of people who had the $1 (prevalence) - it did NOT increase the number of people with $1.
That is how prevalence works!
If the sample size (tests) increases and there is no statistically significant increase in the % - then increasing the sample size only confirmed the prevalence - it did NOT increase the number of people affected.
