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…

Refer to the data set: (1, 2.5), (2.5, 15), (0.5, 2), (-2, 0.5), (0, 1), (1.5, 5)Part a: Make a scatterplot and determine which type of model best fits the data.Part b: Find the regression equation, round decimals to one place.Part c: Use the equation from Part b to determine y when x = 6.
while in high school, Clayton started his T-shirt printing business. The table shows the number of T-shirts Clayton has sold each year since starting his business in 2010 year  2010 2011 2012 2013 2014 2015 2016 number of t-shirts  50 75 175 125 250 350 375 the linear regression equation representing the data shown in the table is y=57.14x + 28.57, where x represents the number of years since 2010 and y represents the number of T-shirts sold. expression unit  contextual meaning  mathematical meaning y       57.14       x       28.57       use the regression equation to predict the number of T-shirts Clayton sold during each given year then compare the prediction to actual number of T-shirt or determine if the prediction is reasonable based on the problem situation. 2012   2014   2016   2018   2024
Use the time/tip data from the table below, which includes data from New York City taxi rides. (The distances are in miles, the times are in minutes, the fares are in dollars, and the tips are in dollars.) Find the regression equation, letting time be the predictor (x) variable. Find the best predicted tip for a ride that takes 30 minutes. How does the result compare to the actual tip amount of $4.70?
