For example, if you conducted a survey to obtain your research results, your samples (participants) were asked to respond to the survey questions. However, you might have had limited ability to gain access to the appropriate type or geographic scope of participants. In this case, the people w...
In a presentation by VWO “Visitors needed for A/B testing” a power of .8 is mentioned as a regular measure. It can be questioned why that should be an acceptable rule? Why could the size of the power, as well as the size of the reliability not be used more dynamically? Solution:...
How to create the perfect home office setup for remote working How to embrace asynchronous communication for remote work How to evaluate a remote job How to repurpose office space in a remote world How to use forcing functions to work remote-first How values contribute to an all-remote...
A thoughtful comment of an anonymous reviewer, however, highlighted that as the learners’ self-assessments were explicitly related to the four types of problems (see above), the accuracy measure would only make sense when a posttest performance of 100% would reflect fully accurate performance on...
Methodology may include limitations due to: Sample size Lack of available or reliable data Lack of prior research studies on the topic Measure used to collect the data Self-reported data The researcher is addressing how the large sample size requires a reassessment of the measures used to collect...
4. Boosting your NPS sample size 5. Create your NPS survey with Survicate false The Net Promoter Score (NPS) is a powerful metric to gauge customer satisfaction and loyalty. But as with any measure, its accuracy and reliability depend on the underlying sample size. In this post, we'...
Statistical measurements of accuracy precision reveal a lab test's basic reliability. These terms, which describe sources of variability, are not interchangeable. A test method can be precise (reliable reproducibility) without being accurate (measuring what it is supposed to measure its true value) ...
You'll find two classifications to descriptive statistics in some pieces, and in some, you'll read about three. People can describe data in different ways. Below, we've classified descriptive statistics into four major types. Measures of central tendency A measure of central tendency also called...
