Another 59 plants receives just water. Which of the following statements provide a valid conclusion that can be drawn from the dotplots? Check all that apply. Group of answer choices The fertilizer had a negative effect on the plant height because the shortest plant is in the fertilizer group. The fertilizer had inconsistent results. The group treated with fertilizer had more variability in height than the untreated group. We cannot compare the two groups because they didn’t contain the same number of plants. The fertilizer had positive results on plant height. The median height is larger for the fertilizer group.
