In this video explaining first problem of Chi square distribution. This problem first follow the binomial distribution method and after Chi square distribution formula. This is very simple method. • The chi-square distribution is a probability distribution that arises in statistics and probability theory. It is often used to test hypotheses and make inferences about population variances and standard deviations. • #easymathseasytricks • Joint Probability Sampling Theory: 18MAT41 17MAT41 • • Joint Probability Sampling Theory • Probability Distributions: 18MAT41 17MAT41 • • Probability Distributions • Calculus of Complex Functions: 18MAT41 17MAT41 • • Complex Analysis Complex Integrations • Curve fitting Statistical Method 18MAT41 17MAT31 • • Statistical Method Curve fitting • LAPLACE TRANSFORM : 18MAT31 • • LAPLACE TRANSFORM • Fourier Transforms,Z-transform : 18MAT31 17MAT31 • • Fourier Transforms,Z-transform: 21MAT... • Fourier Series: 18MAT31 17MAT31 • • Fourier Series: 21MAT31 18MAT31 • Calculus of Variation Numerical Methods 18MAT31 • • Numerical Solution of Second-Order OD... • Numerical Methods ODE's: 18MAT31 17MAT41 • • Numerical Solution of Ordinary Differ... • COMPLEX NUMBER: 18MATDIP31 • • COMPLEX NUMBER: 18MATDIP31 • Differential Calculus:18MATDIP31 • • Differential Calculus:18MATDIP31 • Ordinary differential equation 18MATDIP31,17MATDIP31 • • Ordinary differential equation 18MATD... • Integral Calculus 18MATDIP31,17MATDIP31 • • Integral Calculus 18MATDIP31,17MATDIP31 • Vector differentiation 18MATDIP31,17MATDIP31 • • Vector differentiation 18MATDIP31,17M... • Differential Calculus Partial Differential 18MATDIP31,17MATDIP31 • • Differential Calculus Partial Diffe... • 18MATDIP41 Linear Algebra • • 18MATDIP41 Linear Algebra • 18MATDIP41 Numerical Methods • • 18MATDIP41 Numerical Methods • 18MATDIP41 Higher order ODEs • • 18MATDIP41 Higher order ODEs • 18MATDIP41 Partial Differential Equations • • 18MATDIP41 Partial Differential Equat...
