What is a population?

The entire group being studied

A small group selected for a study

The number of questions in a survey

What is a sample?

A selected portion of the population

The entire population

A survey question

In the formula n=N/(1+Ne^2 ), what does N represent?

Population size

Sample size

Margin of error

Which margin of error is represented by 0.05?

. 0.5%

0.05%

If the computed sample size is 126.2, what should a researcher generally do for this classroom formula?

Round up to 127

Round down to 126

Ignore the decimal

What generally happens to sample size when the margin of error becomes smaller?

It becomes smaller.

It becomes larger.

It remains exactly the same.

1.Which of the following is Slovin's Formula?

n = N/(1 + Ne^2)

n = N/(1 - Ne^2)

n = N/(1 + Ne)^2

Why Do We Need a Sample?

to obtain enough responses to make a reasonable conclusion without having to study the entire population

to know what the respondents better prefer

to identify better results of the study conducted

The margin of error tells us ......

how much the result from a sample may differ from the true result for the entire population

how much the result from a sample is similar from the true result for the entire population

how much the result from a sample may not be fairly different from the true result for the entire population

Why does margin of error matter?

A smaller margin of error means we want a more precise estimate, so we generally need a larger sample.

A bigger margin of error means we want a more precise estimate, so we generally need a larger sample.

A smaller margin of error means we want a more precise estimate, so we generally need a smaller sample.

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
