In order for your survey to be representative for an entire population, you need to calculate the number of respondents: the survey sample size. Here's how!
Suppose that one wishes to estimate a population parameter $\theta$ - for example the population mean or total or proportion of an attribute of the units of the population with an estimator $\hat{\theta}$. Then we would wish the estimate to be close to the true value wit...

The range rule is helpful in many settings. First, it is a very quick estimate of the standard deviation. The standard deviation requires us to first find the mean, then subtract this mean from each data point, square the differences, add these, divide by one less than the number of data...
In a narrow sense, economists frequently measure standard of living using GDP.Per capita GDPprovides a quick, rough estimate of the total amount of goods and services available per person. While numerous, more complex, and nuanced metrics of standard of living have been devised, many of them ...
It formulates a mathematical model to estimate values close to the actual ones. Key terms in Regression Analysis: Dependent variables: The factors you want to predict. Independent variables: The factors that influence the dependent variable. For example, using student data on study hours, ...
Estimate the proportion of the largest group. If you are unsure, use 0.5 as the expected proportion because the closer the two proportions, larger the sample size you will need. For example, if you expected 60 percent of people to vote for the incumbent, you would use 0.6. ...
