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 p…

Expert Solution

Answer to Problem 53E

Advanced Mathematical Concepts: Precalculus with Applications, Student Edition, Chapter 15.2, Problem 53E , additional homework tip 1

Explanation of Solution

Given information:

The amount of sodium in milligrams present in top brands of peanut butter are given,

195,225,210,180,195,194,210,203,233,225,189,210180,225,225,240,178,225,225,195,248,180,255,195225,195,225,225,225,188,225,188,210,240,225,205195,191,240,240,225

Calculation:

Rearrange the data in ascending order,

178,180,180,180,188,188,189,191,194,195,195,195195,195,195,203,205,210,210,210,210,225,225,225225,225,225,225,225,225,225,225,225,225,233,240240,240,240,248,255

Now,

minimum=178maximum=255n=41 (odd)median=21th term=210LQR(Q1)=195UQR(Q2)=225

Now plot box-and −whisker plot,

Advanced Mathematical Concepts: Precalculus with Applications, Student Edition, Chapter 15.2, Problem 53E , additional homework tip 2

To determine

Describe the variability of the data.

Expert Solution

Answer to Problem 53E

The upper quartile range and maximum occupied larger space than lower quartile and minimum.

Explanation of Solution

Given information:

The amount of sodium in milligrams present in top brands of peanut butter are given,

195,225,210,180,195,194,210,203,233,225,189,210180,225,225,240,178,225,225,195,248,180,255,195225,195,225,225,225,188,225,188,210,240,225,205195,191,240,240,225

Calculation:

Now,

minimum=178maximum=255n=41 (odd)median=21th term=210LQR(Q1)=195UQR(Q2)=225

The variability of data is box is situated almost in the middle. The upper quartile range and maximum occupied larger space than lower quartile and minimum.
