Create a Bell Curve in Google Sheets (Step-by-Step)

The term “bell curve” is universally recognized, representing the graphical depiction of the most foundational statistical concept: the normal distribution. This pervasive shape is perfectly symmetrical, defined by the characteristic bell structure where data points concentrate tightly around the central average and gradually decrease in frequency toward the extremes. Understanding and visualizing this distribution is
