1) Draw a plot showing how the cover of Japanese knotweed varies between the Eastern vs. Western side of the Red Maple swamp. the plot should include central tendency (mean, median or mode) of the response variable for each level of the explanatory variable . Your plots must also show the variability/spread (standard deviation, standard error, range, interquartile range, confidence interval) of the response variable for each level of the explanatory variable.
