1. ### What's adequate sample size for single mediator model?

Hi, I have set up a single mediator model to explain cases of COVID-19/million. I generated four regression equations using online software: 1) Cases COVID-19/million = .44234 x # Christians/10,000 + 2475.65082 2) # international adoptions made by a country between 1999 and 2016 =...
2. ### Variable strong in Pearson coefficient calculation but weak in linear regression

Pearson coefficient calculations: # Jews v. Cases/Million r = 0.6199 (p = .000154) # Christians v. Cases/Million r = .5876 (p = .000416) # Int Adoptions v. Cases/Million r = 0.5371 (p = .000675) Tourist Revenue v. Cases/Million r = .483 (p= .005) # Tests/million v. Cases/Million r = 0.3925...
3. ### T Test or Pearson's Coefficient for Testing Colinearity of Two Independent Variables

I originally found that 23 countries that adopt internationally have a significantly higher rate of COVID19 cases/million than the general popululation of countries. two tailed p value = .0010 I now want to know if other independent variables can account for these results. I discovered that...
4. ### My t-test results are significant, but are they meaningful?

I have been researching the question of whether the need to downplay genetics in adoption might weaken a country's response to the coronavirus, which is a piece of genetic material. I ran some t-tests using a t-test calculator. These are two of the results: Those of the 23 richest countries in...
