Linear (the relationship between x and y)
Scatter plot is roughly linear
Residual plot has no curve pattern
2
New cards
Independent: knowing one variable does not help us predict the other
Check 10% condition; explain based on the question
3
New cards
Normal: y is normal for any value of x
Make any graph for the residual and check for strong skewness or outliers
4
New cards
Equals standard deviation: the standard deviation of y is the same for all x values
Check residual plots: dots should vary the same above and below the line (resd = 0)
