1. Explain the difference between proving for important differences and proving for association. If a relationship present between two variables. it is of import to cognize thw way. the way of a relationship can be either positive or negative. An apprehension of the strength of association besides is of import. Research workers by and large categorize the stenght os association as no relationship. weak relationship. moderate relationship. or strong relationship. If a consistent and systematic relationship is non present. so there is no relationship.
2. Explain the difference between association and causing. It depends if we have a additive relationship. which means the strength and nature of the relationship between them remains the same over the scope of both variables. and can be best described utilizing a consecutive line ; or a curvilineal relationship. which means the strength and/or way of the relationship changes over the scope of both variables.
3. What is covariation? How does it differ from correlativity? Covariation is the sum of alteration in one variable that is systematically related to the alteration in another variable of involvement.
4. What are the differences between univariate and bivariate statistical techniques? Univariate focuses on one variable. and bivariate focal points on 2
5. What is arrested development analysis? When would you utilize it? Statistical technique that analyzes the additive relationship between two variables by gauging coefficients for an equation for a consecutive line. One variable is designated as dependent variable and the other is called an independent or forecaster variable.
6. What is the chief job caused by high multicollinearity among the independent variables in a multiple arrested development equation? A state of affairs in which several independent variables are extremely correlated with each other. This characteristic can ensue in trouble in gauging separate or independent arrested development coefficients for the correlative variables.
