Charts: The Possibility to Display Data Visually

We have already learned about some statistical tools, the mean, the median, the mode, the geometric mean, the range, the standard deviation, the variance, the coefficient of variation, and the interquartile range. With these, we have calculated how individuals or objects behave on average with different variables and how the individual persons or objects deviate from it. Numbers, however, are sometimes difficult to convey. This is an important reason why we need charts. Charts help us to convey numbers and create lasting impressions.
