A scatter diagram of the data in the table above is shown in the figure below. The scatter diagram shows a strong linear correlation. (You didn't expect a perfect linear correlation, did you? After all, we are working with camels, dogs, and adult men.) Although we hav considered only three species, Alexander and Jayes were able to show a strong linear correlation for several species. 1- 1 3 4 5 Relative stride length • adult men 1 dogs A camels Finally it is time to estimate the speed of a dinosaur. Consider a large theropod with a leg length of 2.5 m. If the theropod's fossilized footprints show a stride length of 5 m, then its relative stride length is = 2. The least-squares regression line in the figure abe 2.5 m shows that a relative stride length of 2 has a dimensionless speed of about 0.8. If we use 2.5 m for the leg length and 0.8 for dimensionless speed and solve equation (II) for speed, we get Speed- (dimensionless speed) v leg length x g = (0.8)V2,5 x 9,8 * 4.0 m/s. Watch the video below then answer the question.
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.
