Calculating Mean, Median, Range, and Mode from Graphs

Mrs. Fry Fell introduces statistical concepts such as mean, median, range, and mode using charts and graphs. The video provides step-by-step instructions on calculating the mean by summing values and dividing by the count, finding the median by ordering numbers and identifying the middle value, determining the range by subtracting the smallest number from the largest, and identifying the mode as the most frequently occurring number. Various examples and contexts are used to illustrate these concepts, enhancing understanding through practical application.
