According, theses component are assumed to have either the multiplication relationship or additive relationship or model. The analysis of time series data is of particular interest to the businessman because a large proportion of basic data with which he must deal are time series data.

Simple Linear Regression And Correlation

Q.4.3) Explain the concept of regression and correlation, and describe the main properties of Karl-Pearson’s coefficient of correlation.

Answer:
Regression:
Regression is the relationship between one dependent and other independent variable (s). If there is only one independent variable, the regression is said to be simple or linear otherwise the regression is said to be multiple. For example, the yield of wheat is depend upon the fertilizer, seeds, water etc. In this example, the yield of wheat is dependent variable, whit fertilizer; seeds and water are independent variables. The values of independent variables are assumed to be fixed, that is, it is…

class 12 kpk all boards statistics notes chapter number 2 sampling distributions.

Q.1) What is a normal probability distribution? What are the salient features of a normal curve?

NORMAL DISTRIBUTION:
The Normal distribution, which is a suitable model for many distributions of data, is the most important in statistical theory. It was derived from the Binomial distribution. In fact. The normal distribution can be regarded as the limiting form of the Binomial distribution when n, the number of trials, is very large and neither p nor q is very small. Consider the variate.

(Normal Distribution)

Z=X –np / √npq

Where X is the Binomial variate with mean np and standard deviation √npq so that…
