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.

Fill in the remainder of the following table and use it to answer the questions below. Infected Not Infected Total Positive Test Negative Test Total 400 99,600 100,000
This is the question im stuggling with To study peanut allergies in children, 320 babies who were at high risk for developing peanut allergies were given peanuts. 3.2% of these babies developed peanut allergies. How many babies in the study developed peanut allergies? This is what i did: i cross multiply x with 100 and 3.2 with 320 then divided both sides by 100 to get x=10.24. I dont think its right because to me it doesnt make any sense my question is where did i go wrong? How many babies did not develop peanut allergies?
