do metal electrical boxes have to be grounded So while you may not have to connect the equipment grounding conductor to the box, the boxes do have to be grounded and bonded. Since you're using EMT, the boxes can be grounded and bonded via the conduit. Box plots, also called box-and-whisker plots or box-whisker plots, give a good graphical image of the concentration of the data. They also show how far the extreme values are from most of the data.In descriptive statistics, a box plot or boxplot (also known as a box and whisker plot) is a type of chart often used in explanatory data analysis. Box plots visually show the distribution of numerical data and skewness by .
