Given the fоllоwing bоx аnd whisker plot displаying English Essаy Scores, what can be said about the shape of the distribution? The image is a horizontal box plot labeled “English Scores.” The number line runs from 0 to 90 in increments of 5. The data values are represented by a single box-and-whisker plot. The minimum score is 24, and the maximum score is 90. The lower quartile (Q1) is at 41, and the upper quartile (Q3) is at 84. The box extends between these quartiles, representing the middle 50 percent of the scores. The median is marked at approximately 77, closer to the upper quartile. The distribution shows that most English scores fall between 41 and 84, with a slightly right-skewed shape since the median is closer to the higher end of the box. This indicates that while most students scored moderately high, a few lower scores pulled the minimum down to 24.
