confidence level

Confidence level is a statistical term that indicates how sure we are that our sample results reflect the true characteristics of a larger population. It’s expressed as a percentage, commonly 90%, 95%, or 99%. A 95% confidence level means that if we were to take many samples and calculate the results, we would expect 95% of those samples to reflect the true population parameter within a specified range. Essentially, it helps us gauge the reliability of our findings, giving us a measure of certainty about how much we can trust our conclusions.
