Advantages of Simple Random Sample - ANS-Free of bias
Easy and cheap to put into effect
Each sampling unit has equal risk of choice
Advantages of Stratified Sampling - ANS-Population need to genuinely labeled into distinct
strata
Advantages of Systematic Sampling - ANS-Simple and quick to use
Suitable for massive samples
alternative hypothesis - ANS-Tells us approximately the parameter if your assumption is
inaccurate

Cleaning the information - ANS-The procedure of doing away with anomalies from a records
set.
Continuous Variable - ANS-A variable which could take any price in a given range
Correlation - ANS-A degree of the linear relationship among two variables
critical place - ANS-the region inside the tails of the assessment distribution wherein the null
speculation can be rejected
Disadvantage of a census - ANS-Time eating and high-priced
Hard to process huge quantity of facts
Disadvantage of a pattern - ANS-The facts won't be as accurate
The statistics may not be large enough toggle records approximately the populace
