To find this out, you need to be clear about who does and doesn’t fit into your group. For example, if you want to know about dog owners, you’ll include everyone who has at some point owned at least one dog. (You may include or exclude those who owned a dog in the past, ...
as an estimate of the population. A sample will never perfectly mirror the population, because they are just a fraction of the population and so may not be representative of the whole group. But in real life, we usually can’t count every population member, so we have to work with ...

A confidence interval is a range of likely values for the population parameter based on a point estimate (e.g., the sample mean), a confidence level (e.g., 95%) and the sampling variability or standard error of the point estimate. Usually, analysts will include a 95% or 99% confidence...
More data and a more principled approach to regression, as explained in Harrell's course notes, will give you more generally reliable results. *When you go to the other end of the confidence interval, the lower 95% limit on the HR scale consistent with that point estimate and upper limit ...

Now, by random chance you might get more responses from very happy or very unhappy customers. This results in the actual score being lower or higher than sample NPS of responses you have collected collected. The problem is: How do you know how close your sample NPS estimate is to the popu...
This should be cheap. It cost <1c to make this post with all the testing. So in theory you could do 100s of methods sections for <100USD. However, if you are testing back and forwards a lot or using full papers the cost could add up. It will be hard to estimate this until peop...
When it comes to exact rates, everything depends on the location and experience of a development team. For clarity, below are the average hourly rates of software developers in different geographic regions. The stats cover the US and Canada, Western and Eastern Europe. Average web developer hour...
An estimator (or estimate) is a statistic that’s used to approximate a population parameter. While there are several types of estimators, the word “estimator” on its own usually refers to a point estimate. A point estimate is a single value (as opposed to an interval, like aconfidence ...
