Correlation only indicates the degree and direction of relationship between twovariables. It does not, necessarily connote a cause-effect relationship. Even when there are grounds to believe the causal relationship exits, correlationdoes not tell us which variable is the cause and...

DEFINITION: Correlation is a statistical measurement of the relationship between twovariables.
CORRELATION ANALYSIS:...
Correlation analysis:
The correlation analysis refers to the techniques used in measuring the closeness of the relationship between the variables. The degree of relationship between the variables under consideration is measured through the correlation analysis. And the measure of correlation called...
between two random variables or two sets of data. Correlation refers to any of a broad class of statistical relationships involving dependence.
Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for...

Q1. What do you mean by sample survey? What are the different sampling methods? Briefly describe them.
Ans.
Sample is a finite subset of a population drawn from it to estimate the characteristic of the population. Sampling...
linear relationship between two explanatory variables. Twovariables are perfectly collinear if there is an exact linear relationship between the two. For example, X1 and X2 are perfectly collinear if there exist parameters λ0 and λ1 such that, for all observations i, we have
X2i = λ0 + λ1X1i.

Hindsight Bias- the tendency to believe, after learning an outcome, that one would have foreseen it. (Also known as the I-knew-it-all-along phenomenon.)

A variable is discrete if you can list its possible values. Otherwise it is called continuous. A dummy variable can take on two values, 0 or 1. We use dummy variables to indicate something, 1 if that something “happened”, 0 if it did not. Histograms height of each bar = # of observations / “frequency”...
