The table shows the heightsh (in feet) of a sponge t seconds after it was dropped by a window cleaner on to Time, t 1 1.5 2.5 3 Height, h 280 264 244 180 136 a. Use a graphing calculator to create a scatter plot. Which better represents the data, a line or a parabola? Expla A parabola best represents the data because there is not a constant rate of change. b. Use the regression feature of your calculator to find the model that best fits the data. The model is h = c. Use the model in part (b) to predict when the sponge will hit the ground. Round your answer to the nearest hundredth. about 4.18 v seconds
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.
