In statistics, uniform distribution refers to a type of probability distribution in which all outcomes are equally likely. Probability distributions can help you decide the probability of a future event. Uniform distribution for a deck of cards is expected because the likelihood of drawing a heart, ...
Asymmetrical distribution is a situation in which the values of variables occur at irregular frequencies and the mean, median, and mode occur at different points. An asymmetric distribution exhibitsskewness. In contrast, a Gaussian ornormal distribution, when depicted on a graph, is shaped like a ...
Frequency distribution is found by tallying up the number of data points in each category. The formula is, then, the sum total for each category.What is Frequency Distribution? There are many ways to present data in statistics. One of these methods is a frequency distribution. What is a fr...

The t distribution has only one parameter, the degrees of freedom (DF). In t-tests, DF are linked to the sample size. For 1-sample and paired t-tests, DF = N – 1. For 2-sample t-tests, it equals N – 2. Hence, as the sample size increases, the DF also increases. Learn mo...
