A boxplot shows the median exactly in the center of the box, and both whiskers are approximately the same length. The distribution is most likely ______________________.
Use the given data to construct a boxplot and identify the 5-number summary.
Reaction Times: A group of 14 students participated in a reflex test, where their reaction times (in milliseconds) were recorded. The recorded reaction times are as follows:
220 250 275 240 230 290 310 260 245 270 280 255 265 300\(\text{220 250 275 240 230 290 310 260 245 270 280 255 265 300}\)
i. Identify any outliers
ii. Draw a modified box-and-whisker plot that represents the following data set.
5858, 6161, 6565, 6262, 7070, 7272, 7575, 6363, 6868, 9090, 6767, 6464
The heights (in centimeters) of plants grown under two different light conditions, Condition A and Condition B, are shown using side-by-side box and whisker plots. Describe the distribution shape for each condition and state which condition exhibits more consistent plant heights.
