Is 30 respondents enough for a survey? ›

We generally recommend a panel size of 30 respondents for in-depth interviews if the study includes similar segments within the population. We suggest a minimum sample size of 10, but in this case, population integrity in recruiting is critical.

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.

Response rates approximating 60% for most research should be the goal of researchers and certainly are the expectation of the Editor and Associate Editors of the Journal.

Microwaves are a specific category of radio waves that can be defined as radiofrequency radiation where frequencies range upward from several hundred megahertz (MHz) to several gigahertz (GHz).

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. This exceeds 1000, so in this case the maximum would be 1000.

While there are no hard and fast rules around how many people you should involve in your research, some researchers estimate between 10 and 50 participants as being sufficient depending on your type of research and research question (Creswell & Creswell, 2018).

So, what is a good survey response rate? Factors that impact this include, how engaged your customers are with your brand, and whether you're delivering surveys in a way that's easy for them. Nevertheless, a good survey response rate ranges between 5% and 30%. An excellent response rate is 50% or higher.

However, more generally and irrespective of your survey type, typical survey response rates can lie anywhere in the region between the 5% to 30% range, with those surveys distributed from unknown senders tending to be at the lower end of this scale.

As a very rough rule of thumb, 200 responses will provide fairly good survey accuracy under most assumptions and parameters of a survey project. 100 responses are probably needed even for marginally acceptable accuracy.

A good good NPS response rate is one that is above around 20%, subject to having enough total responses. You can see from this data published by CustomerGauge, using their extensive CustomerGauge NPS Benchmarks Survey, that most organisations (~51%) have response rates of 20% or higher.

What is a typical response rate for a survey? ›

“Response rates vary widely for different types of surveys. Customer satisfaction surveys and market research surveys often have response rates in the 10% – 30% range. Employee surveys typically have a response rate of 25% – 60%.

As we move to larger companies, we can scale our expectations down – with 500 employees, we will probably get a good sense of where the company is with a 70% rate of participation, so 70-80% is a good benchmark.

Frequency is measured in the unit hertz (Hz), referring to a number of cycles per second. One thousand hertz is referred to as a kilohertz (kHz), 1 million hertz as a megahertz (MHz), and 1 billion hertz as a gigahertz (GHz). The range of the radio spectrum is considered to be 3 kilohertz up to 3,000 gigahertz.

The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz).

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).

“A minimum of 30 observations is sufficient to conduct significant statistics.” This is open to many interpretations of which the most fallible one is that the sample size of 30 is enough to trust your confidence interval.

The larger the sample, the more confident you can be that the analysis is valid. Results derived from samples smaller than 30 simply cannot be trusted to be valid. It is not so much that "30 should be enough;" it is more that "less than 30 is almost certainty not enough."

Sampling ratio (sample size to population size): Generally speaking, the smaller the population, the larger the sampling ratio needed. For populations under 1,000, a minimum ratio of 30 percent (300 individuals) is advisable to ensure representativeness of the sample.

Many statisticians concur that a sample size of 100 is the minimum you need for meaningful results. If your population is smaller than that, you should aim to survey all of the members. The same source states that the maximum number of respondents should be 10% of your population, but it should not exceed 1000.
