1. correlation: correlation does not mean causation one of the major misconceptions about correlation is that a relationship between two variables means causation; that is, one variable causes changes in the other variable. there is a particular tendency to make this causal error, when the two variables seem to be related to each other. what is one instance where you have seen correlation misinterpreted as causation?

2. linear regression linear regression is used to predict the value of one variable from another variable. since it is based on correlation, it cannot provide causation. in addition, the strength of the relationship between the two variables affects the ability to predict one variable from the other variable; that is, the stronger the relationship between the two variables, the better the ability to do prediction. what is one instance where you think linear regression would be useful to you in your workplace or chosen major? describe including why and how it would be used.

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.
