In Linear Regression these two variables are related through an equation, where exponent (power) of both these variables is 1. Mathematically a linear relationship represents a straight line when plotted…

Chi-Square test is a statistical method to determine if two categorical variables have a significant correlation between them. Both those variables should be from same population and they should be…

Correlation refers to some statistical relationships involving dependence between two data sets. Simple examples of dependent phenomena include the correlation between the physical appearance of parents and their offspring, and…

The p-value is about the strength of a hypothesis. We build hypothesis based on some statistical model and compare the model's validity using p-value. One way to get the p-value…

The Bernoulli distribution is a special case of the Binomial distribution where a single experiment is conducted so that the number of observation is 1. So, the Bernoulli distribution therefore…

A Poisson distribution is a distribution that shows the likely number of times that an event will occur within a pre-determined period of time. It is used for independent events…

The binomial distribution model deals with finding the probability of success of an event which has only two possible outcomes in a series of experiments. For example, tossing of a…

The normal distribution is a form of presenting data by arranging the probability distribution of each value in the data. Most values remain around the mean value making the arrangement…

In statistics, variance is a measure of how far a value in a data set lies from the mean value. In other words, it indicates how dispersed the values are.…

Mathematically central tendency means measuring the center or distribution of location of values of a data set. It gives an idea of the average value of the data in the…
