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.

While the mail-order DVD rental market has slowed with the advent of streaming, mail-order is still the only way to find rare movies. Raredvds.biz is considering moving into the rental business after considerable success selling DVDs. To gauge their customer service, they are considering the case of the 1980 film The Monster Club featuring Vincent Price. Raredvds.biz expects to have one copy of the DVD. Based on data collected from customers, Raredvds.biz believes that the average time between orders for the film will be about 10 days with a coefficient of variation of one. Using customer data, the company also believes that including shipping time, both ways, the DVD will on average spend seven days in service, with a coefficient of variation of one. How long does a customer wait on average before being shipped the DVD?
An observational study is conducted to investigate the association between age and total serum cholesterol. The correlation is estimated at r = 0.35. The study involves n=125 participants and the mean (std dev) age is 44.3 (10.0) years with an age range of 35 to 55 years, and mean (std dev) total cholesterol is 202.8 (38.4). Estimate the equation of the line that best describes the association between age (as the independent variable) and total serum cholesterol. Estimate the total serum cholesterol for a 50-year old person. Estimate the total serum cholesterol for a 70-year old person. d. For part c, why or why not might this estimate be appropriate?

Studies have shown that people who suffer sudden cardiac arrest have a better chance of survival if a defibrillator shock is administered very soon after cardiac arrest. How is survival rate related to the time between when cardiac arrest occurs and when the defibrillator shock is delivered? The accompanying data give y = survival rate (percent) and x = mean call-to-shock time (minutes) for a cardiac rehabilitation center (in which cardiac arrests occurred while victims were hospitalized and so the call-to-shock time tended to be short) and for four communities of different sizes.
