Binomial Distribution
by: tutorvistateam, 4 pagesIn probability theory and statistics, the binomial distribution is the discrete probability distribution of the number of successes in a sequence of n independent yes/no experiments, each of which ...
Chi Square Test
by: tutorvistateam, 4 pagesThe chi-square distribution is commonly used to make inferences about a population variance. If a population follows the normal distribution, you can draw a sample of size N from this distribution ...
Coefficient of Determination
by: tutorvistateam, 4 pagesIn statistics, the coefficient of determination R2 is used in the context of statistical models whose main purpose is the prediction of future outcomes on the basis of other related information. It ...
Negative Correlation
by: tutorvistateam, 4 pagesA relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1.00, while a 0 ...
Positive Correlation
by: tutorvistateam, 4 pagesEstrogen receptor-α (ER) and human epidermal growth factor receptor 2 (HER2) positivity are inversely correlated by standard criteria. However, we investigated the quantitative relation between ...
Circumference of a Circle Formula
by: tutorvistateam_team, 4 pagesIn the above diagram, ‘O’ is the centre of the circle, the white line is its radius and the black outline is the perimeter or circumference of the circle. Notice that a circle partitions ...
Differential Equations
by: tutorvistateam_team, 4 pagesToday I am going to tell you about a very interesting field of mathematics: differential equations. A differential equation is an equation for the functions which are unknown and are consisting of ...
How to Find the Area of a Circle
by: tutorvistateam_team, 4 pagesCircle is a geometrical round shape figure like a ring, tire etc. Circle includes many terms such as diameter, radius, area, circumference, and many more. In this session we are going to discuss How ...
How To Multiply Fractions
by: tutorvistateam_team, 4 pagesA fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a ...
Normal Distribution
by: tutorvistateam_team, 4 pagesIn mathematical analysis, distributions (or generalized functions) are objects that generalize functions. Distributions make it possible to differentiate functions whose derivatives do not exist in ...
