Concept explainers

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

What conclusion should be made at the a = 0.05 level?
A camival game is designed so that approximately 10%
of players will win a large prize. If there is evidence that
the percentage differs significantly from this target, then
adjustments will be made to the game. To investigate, a
random sample of 100 players is selected from the
large population of all players. Of these players, 19 win
a large prize. The question of interest is whether the
data provide convincing evidence that the true
proportion of players who win this game differs from
0.10. The computer output gives the results of a z-test
for one proportion.
O Because the P-value <a = 0.05, there is convincing
evidence that the true proportion of players who win
this game differs from 0.10.
O Because the P-value <a = 0.05, there is convincing
evidence that the true proportion of players who win
this game differs from 0.19.
O Because the P-value <a = 0.05, there is not
convincing evidence that the true proportion of
players who win this game differs from 0.10.
Test and CI for One Proportion
O Because the P-value <a = 0.05, there is not
