Two-Variable Statistical Calculator. Introduction. Statistical Applets. Choose a data set on the first tab below, then click the other tabs to view or manipulate the data, see summary statistics including the correlation and equation of the least-squares regression line, or view a scatterplot or residuals plot of the data. ...

The Two-Variable Statistics Calculator serves as a tool to determine the Mean (Average) from a dataset comprising two variables. It simplifies the process of computing the Mean, a fundamental statistical measure used across various fields to understand central tendencies within data sets.

Multiple Regression Calculator. This simple multiple linear regression calculator uses the least squares method to find the line of best fit for data comprising two independent X values and one dependent Y value, allowing you to estimate the value of a dependent variable (Y) from two given independent (or explanatory) variables (X 1 and X 2).. The line of best fit is described by the equation ...

Two-variable Statistical Calculator (Correlation and Regression) Statistical investigations are often interested in changes in a variable over time, or relationships among several variables. This applet describes straight-line relationships between two variables using the methods of correlation & regression.

Bivariate data consists of two variables, often denoted as X and Y, with an associated relationship. A Bivariate Data Calculator, categorized under statistical calculators, utilizes this data to determine the strength, direction, and type of relationship between these two variables. Detailed Explanation of the Calculator’s Working

A Correlation Coefficient Calculator measures the strength and direction of the linear relationship between two variables using Pearson's or ...

Calculates descriptive statistics for two-variable data sets (variables x and y) with equal numbers of observations. Data includes mean, occurrences, sums, standard deviations, variances, minimums and maximums. It also calculates linear, natural log, log, exponential and power regressions with prediction capabilities.

1. Two tailed test example: A factory uses two identical machines to produce plastic plates. You would expect both machines to produce the same number of plates per minute. Let μ1 = average number of plates produced by machine1 per minute. Let μ2 = average number of plates produced by machine2 per minute. We would expect μ1 to be equal to μ2.

The calculator allows you to model the linear relationship between two or more variables online. The regression statistics calculator therefore provides you with all relevant statistical values for your data. If you want to calculate the regression line, all you need to do is read the B values in the output table. The result of the regression ...

8. Changing the correlation. Use the Two-Variable Statistical Calculator applet to demonstrate how outliers can affect correlation. (a) What is the correlation between lean body mass and metabolic rate for the 12 women in Exercise 4.3 (page 75)? (b) Make a scatterplot of the data with two new points added. Point A: mass 65 kilograms, metabolic rate 1761 calories.

Our Regression Line & Coefficient of Determination Calculator is an invaluable tool for analyzing linear relationships in your data. By simply entering your x‑values and y‑values, you can obtain the best‑fit regression line and understand how well the model explains the variability through the \(R^2\) value.
