What is the effect of increasing the sample size on the margin of error in statistical analysis?

Back

Increasing the sample size decreases the margin of error, leading to more accurate estimates.

2.

FLASHCARD QUESTION

Front

Define stratified sampling in research. How is it different from other sampling techniques?

Back

Stratified sampling involves dividing a population into subgroups (strata) and sampling from each stratum. It ensures representation from all groups, unlike convenience or cluster sampling.

What is a piecewise-defined function? Provide an example.

FLASHCARD QUESTION

Front

How do you find the center of a circle given its general equation?

Back

The center of a circle in the form (x - h)^2 + (y - k)^2 = r^2 is (h, k). For the equation x^2 + y^2 + 14x - 12y + 49 = 0, the center is (-7, 6).
