What is a statistically significant Answers. Data is statistically significant if the p (probability) value is below a certain level (ex: 5% or 1%). The p value describes how often one would receive the results they got if left to chance alone., quantitative research. This paper only examines sample size considerations in quantitative research. Factors that influence sample sizes Sufficient sample size is the minimum number of participants required to identify a statistically significant difference if a difference truly exists.

When you conduct a survey, you want to make sure that you have enough people involved so that the results will be statistically significant. However, the larger your survey, the more time and money you will have to spend to complete it. To maximize your results and minimize your cost, you need to plan ahead to determine the sample size of the Sample Size Calculator. This Sample Size Calculator is presented as a public service of Creative Research Systems survey software. You can use it to determine how many people you need to interview in order to get results that reflect the target population as precisely as needed. You can also find the level of precision you have in an existing sample.

In other words, if the null hypothesis is false, what is the probability that your "sample" will produce statistically significant results at the p < 0.05 level of significance? If the likelihood is good (e.g., at least 80% chance), for an acceptable "effect size", then your sample size would be considered adequate (i.e. statistically powerful).

If a polling firm is trying to determine voter satisfaction with Congress, and its sample size is one, then the results are going to be meaningless (but easy to obtain). Notice that our p-value, 0.02116, would not be significant if we had used a threshold of 0.01. Someone who wants to prove the opposite point in our study can simply manipulate the p-value. Anytime we examine a study, we should think about the p-value and the sample size in addition to the conclusion.
