The closer the data points fall along a line, the stronger the relationship” (Hiner Quizlet).]]> 2018-08-28 22:29:44 UTC https://padlet.com/dowens22/d52kzx7pu3m3/wish/276062891 Explain the 5 types of correlation dowens22 https://padlet.com/dowens22/d52kzx7pu3m3/wish/276063068 "Positive Correlation: A positive correlation is a correlation in the same direction.
Negative Correlation: A negative correlation is a correlation in the opposite direction. 
Linear Correlation:  When the change in one variable results in the constant change in the other variable, we say the correlation is linear. When there is a linear correlation, the points plotted will be in a straight line
Scatter Plot Correlation: A scatter plot is a type of mathematical diagram using cartesian coordinates to display values for two variables for a set of data. Scatter plots will often show at a glance whether a relationship exists between two sets of data. The data displayed on the graph resembles a line rising from left to right. Since the slope of the line is positive, there is a positive correlation between the two sets of data.
Non Linear Correlation: 
When the amount of change in one variable is not in a constant ratio to the change in the other variable, we say that the correlation is non linear" Correlation. (n.d.).

(2015). ]]> 2018-08-28 22:33:54 UTC https://padlet.com/dowens22/d52kzx7pu3m3/wish/276063331 What is the correlation coefficient? dowens22 https://padlet.com/dowens22/d52kzx7pu3m3/wish/276063366 “The correlation coefficient, r, from linear regression, indicates the strength of the correlation. The closer r is to 1 or -1, the more closely the data resembles a line”(Hiner Quizlet).]]> 2018-08-28 22:34:16 UTC https://padlet.com/dowens22/d52kzx7pu3m3/wish/276063366 Works Cited dowens22 https://padlet.com/dowens22/d52kzx7pu3m3/wish/276063460 Correlation.
