What is its importance in statistics? Central Limit Theorem The Central Limit Theorem (CLT) is a cornerstone of probability and statistics. The theorem states that as the sample size increases, the mean distribution among several samples will resemble a Normal Distribution. When you don'...
It is recommended you compute both the mean and median for your data. If there is a significant difference, you might look for an extreme value and understand what happened. For example, if your mean is 22.44 but your median is 8, you might look for a high number since the mean seems...
There is a growing feeling in the statistical community that significant changes must be made in statistical education. Statistical education has traditionally focused on developing knowledge and skills and assumed that students would create value for the subject in the process. This approach hasn't ...
As adjectives the difference between significant and significative is that significant is signifying something; carrying meaning while significative is...
There’s also a common trap where "significant" is used interchangeably with "important." While this might work in everyday conversation, in the realm of statistics, "significant" has a very specific meaning—it refers to the likelihood that a result is not due to random chance. That said,...

Cluster analysis is the grouping of objects based on their characteristics such that there is high intra-cluster similarity and low inter-cluster similarity.
On the other hand, quantitative data is relatively straightforward to collect and analyze. Because qualitative data cannot easily be reduced to numbers or statistics, researchers need to reorganize the data in more structured and meaningful ways for analysis. A qualitative researcher often has to read...
A p-value of 0.05 or lower is generally considered statistically significant. P-value can serve as an alternative to—or in addition to—preselected confidence levels for hypothesis testing. Jessica Olah / Investopedia Understanding P-Value
