## How many respondents is acceptable in quantitative research?

Researchers disagree on what constitutes an appropriate sample size for statistical data.

My rule of thumb is to attempt to have 50 respondents in each category of interest (if you wish to compare male and female footballers, 50 of each would be a useful number)..

## How do we calculate sample size?

How to Find a Sample Size Given a Confidence Interval and Width (unknown population standard deviation)za/2: Divide the confidence interval by two, and look that area up in the z-table: .95 / 2 = 0.475. … E (margin of error): Divide the given width by 2. 6% / 2. … : use the given percentage. 41% = 0.41. … : subtract. from 1.

## Why is 30 a good sample size?

One may ask why sample size is so important. The answer to this is that an appropriate sample size is required for validity. If the sample size it too small, it will not yield valid results. … If we are using three independent variables, then a clear rule would be to have a minimum sample size of 30.

## How many respondents do I need for a survey?

## How do you calculate respondents?

To know how many people you should send your survey to, you want to take your sample size (how many responses you need back) divided by the response rate. For example, if you have a sample of 1,000 and an estimated response rate of 10%, you would divide 1000 by . 10.

## What is an appropriate sample size for a survey?

A good maximum sample size is usually 10% as long as it does not exceed 1000. A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a population of 200,000, 10% would be 20,000.

## What is a good percentage of survey responses?

A survey response rate of 50% or higher should be considered excellent in most circumstances. A high response rate is likely driven by high levels of motivation to complete the survey, or a strong personal relationship between business and customer. Survey response rates in the 5% to 30% range are far more typical.

## How do you know if a survey is statistically valid?

## How many questionnaires is a good sample?

400 questionnairesFor most audience research projects, we recommend collecting 400 questionnaires. We are not alone in this general rule of thumb—400 is considered by some researchers (and market researchers in particular) to be the “magic number” in the world of sample sizes.

## What is the slovin’s formula?

– is used to calculate the sample size (n) given the population size (N) and a margin of error (e). -It is computed as n = N / (1+Ne2). When taking statistical samples, sometimes a lot is known about a population, sometimes a little and sometimes nothing at all. …

## How do you know if a sample is statistically significant?
