when does the slope of predicting yield change when is rainfall related to yield how can i test if my data is correlated with rainfall what is the relationship of rainfall and yield on a model does rainfall affect yield when is rainfall independent from yield if soil rainfall is independent which is the best way to test for variation in the slope of yield? quizlet how to measure the slopes of a rainfall how to find how the slopes between rainfall and yield are different why are slopes of soil yield different for each state which of the following is a measure of yield when the slopes of rain and yield are independent variables that are not independent or correlated. which is true of rainfall? are rainfall and yield related? how to find if the yield vs rainfall is similar across states if rainfall is independent of one another does the relationship between the slopes of yield and rainfall is rainfall independent of each other does rainfall and rainfall depend why are yields and precipitation different
