Variance vs Covariance Variance and covariance are two measures used in statistics. Variance is a measure of the scatter of the data, and covariance indicates the degree of change of two random variables together. Variance is rather an intuitive concept, but covariance is defined mathematically in not that intuitive at first. More about Variance […]
Difference Between Correlation and Covariance
Correlation vs Covariance Correlation and covariance are closely related concepts in theoretical statistics. They are important in determining the relationship between two random variables. What is Correlation? Correlation is a measure of the strength of the relationship between two variables. The correlation coefficient quantifies the degree of change of one variable based on the […]
Difference Between Parameter and Statistic
Parameter vs Statistic Consider these questions; what is the average income of a person in your country, what is the average height of women in the world, and what is the average weight of the eggs produced by certain breeds of fowl? It is impossible to do a survey that includes all the subjects of […]
Difference Between Regression and ANOVA
Regression vs ANOVA Regression and ANOVA (Analysis of Variance) are two methods in the statistical theory to analyze the behavior of one variable compared to another. In regression, it is often the variation of dependent variable based on independent variable while, in ANOVA, it is the variation of the attributes of two samples from […]
Difference Between Definite and Indefinite Integrals
Definite vs Indefinite Integrals Calculus is an important branch of mathematics, and differentiation plays a critical role in calculus. The inverse process of the differentiation is known as integration, and the inverse is known as the integral, or simply put, the inverse of differentiation gives an integral. Based on the results they produce the […]
Difference Between Complementary and Supplementary Angles
Complementary vs Supplementary Angles Geometry, a pillar of mathematics, is one of the oldest forms of mathematics. Geometry is the branch of mathematics which study the shapes and size of the figures and space. The basic concepts of geometry in the present day mathematical form were developed by the ancient Greeks. The development culminated […]
Difference Between Probability and Statistics
Probability vs Statistics Probability is a measure of the likelihood of an event to occur. Since probability is a quantified measure, it has to be developed with the mathematical background. Specifically, this mathematical build of the probability is known as the probability theory. Statistics is the discipline of collection, organization, analysis, interpretation, and presentation […]
Difference Between Regression and Correlation
Regression vs Correlation In statistics, determining the relation between two random variables is important. It gives the ability to make predictions about one variable relative to others. Regression analysis and correlation are applied in weather forecasts, financial market behaviour, establishment of physical relationships by experiments, and in much more real world scenarios. What is […]
Difference Between Bar Graph and Histogram
Bar Graph vs Histogram In statistics, summarizing and presentation of the data is important. It can be done either numerically using descriptive measures or graphically using the pie graphs, bar graphs, and many other graphical representation methods. What is a Bar Graph? Bar graph is one of the main graphical representation methods in statistics. […]
Difference Between Descriptive and Inferential Statistics
Descriptive vs Inferential Statistics Statistics is the discipline of collection, analysis, and presentation of data. Theory of statistics is divided into two branches on the basis of the information they produce by analyzing the data. What is Descriptive Statistics? Descriptive statistics is the branch of statistics that describe the main properties of a data […]
