An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants all 3 varieties of the seeds on each of 5 different patches of fields. She then measures the crop yield in bushels per acre. She has found out that the different varieties do have an impact on crop yield. Which of the following tests will be the most appropriate to find out which variety will produce the highest yield?
Outlier
An outlier is an observation in a data set that is distant from other observations, often indicating variability in measurement or a potential error.
Categorical Variable
A type of variable that can take on one of a limited, and usually fixed, number of possible values, assigning each individual or other unit of analysis to a particular group or nominal category.
Cubed-Root Transformation
A statistical technique used to stabilize variance, make the data more closely conform to a normal distribution, or improve the interpretability of data with skewed distributions.
Log Transformation
A mathematical operation that replaces a variable with the logarithm of that variable to help normalize data or manage skewed distributions.
