The histogram gives us a good overview of the data. At a glance, we can see that these data clearly are not normally distributed. They are right skewed. The peak is around 27%, and the distribution extends further into the higher values than to the lower values.Learn more about skewed ...
Median (Even Values) = Mean of middle numbers Median (Odd Values) = Middle number Let's use the same dataset as used above to understand the median with an example. First, we must arrange the values in ascending or descending order to find the median. Rearranged values: 2, 4, 4, ...
How to find the degrees of freedom when using the t-distribution to estimate or test the mean of a sample from a single population? Student t Distribution: The degrees of freedom are associated with several statistical distributions such as Student'...

than we may think. This depends largely on our understanding of the shape and distribution of our data set. If our data set happens to follow the normal distribution, we can use z-scores and the Standard Normal Probabilities table to help us find the percentage of...

Survey data analysis is all about making sense of the answers you get from surveys. It means taking the raw responses, organizing them, cleaning up any errors, and using statistics to find patterns and trends. The goal is to turn those answers into clear, useful insights that can help with...
The mean of a negatively skewed distribution is less than the median and the mode. These facts result in an important rule of thumb that you can use to find out if a particular distribution is positively or negatively skewed: If the mean is greater than the mode or less than the median ...
P-values are usually calculated using statistical software or p-value tables based on the assumed or knownprobability distributionof the specific statistic tested. While the sample size influences the reliability of the observed data, the p-value approach to hypothesis testing specifically involves calcu...
