Question

Suppose that a recent study found that teachers who utilize techniques of active learning had students who were 20% more likely to pass the class than students in classes where teachers did not use active learning. Suppose that this difference was found to be statistically significant. What does this mean? Group of answer choices a.Being statistically-ignificant means that this observed difference is very likely: it occurs almost at least 95% of the time. b.Being statistically-significant means it is sufficient to conclude that roundup is the cause for the lymphoma increase. cBeing statistically-significant means that this difference is important. d.Being statistically-significant means it is very unlikely if due entirely to chance

Answer 1

Answer:The correct answer is:

d. Being statistically-significant means it is very unlikely if due entirely to chance.

When a difference is found to be statistically significant, it means that the observed difference is unlikely to have occurred solely due to random chance. In other words, there is a high level of confidence that the observed effect is real and not just a fluke or random variation in the data. Typically, in scientific research, a significance level of 95% or higher (commonly 95% or 99%) is used to determine statistical significance, which means that there is a 5% or lower chance that the result is due to random chance.
