In this chapter, we discussed several aspects of descriptive statistics. A descriptive statistic is commonly referred to as a summary statistic that quantitatively describes a given dataset. We discussed the most common summary measures used in this field, including measures of central tendency (mean, median, and mode) and measures of variability (standard deviation, minimum, maximum, kurtosis, and skewness). 

In the next chapter, we will continue more advanced descriptive statistics by using grouping techniques. These grouping techniques are provided by the pandas library.
