Simple Random (sampling type) - Answer- Every member of the population has an equal chance of being selected -it's simple and it's random. Systematic (sampling type) - Answer- Every kth member of the population is selected for the sample. It's easy to do manually, but there can be periodicity which allows for bias. Stratified (sampling type) - Answer- Divide the population into mutually exclusivegroups based on one variable (strata). Next, randomly and proportionally select from those s...

Linear Discriminant Analysis (LDA) Questions & Accurate answers, VERIFIED. Why do we need another method from logistic regression? - LDA does not suffer from the problem of when the classes are separated, the parameter estimates for the logistic regression are surprisingly unstable. Also if n is small and the distribution of the predictors X is approximately normal in each of the classes, the LDA is more stable. Thirdly, LDA is popular when we have more than two response classes. Prior p...

Difference between categorical and quantitative data Correct Answer Quantitative variables provide numerical information. Categorical variables yield data that can only be considered as categories. Differences in the definitions of a Parameter, Population, Statistic and a Sample Correct Answer Parameter: Numbers that summarize data from a population Population: Entire collection of a group Statistic: The probability of obtaining a result or numbers that summarize the data from a sample S...
