The “least square regression model” is based on the “best fit” line to the data. This will determine a line equation for LINEAR data that will minimize “residual” values (difference between actual and “predicted” ) True or False Correlation tells us if there is a relationship between two numeric variables and how strong that relationship is: True or False

Question 312 marks An study was conducted using data from pedometers of 68 randomly selected participants. The researchers wanted to know if the number of steps taken by a participant (Steps) could be predicted using the time they spent walking (Minutes). The data are available on MyUni in the file Steps.csv. 2 (a) Produce a scatterplot of Steps vs Minutes and describe any relationship between these two variables. (b) Perform a linear regression analysis on this data in MATLAB and...
