As a result, it will be easier to understand the distribution of the variables in your data set: Which values are central to, or typical of your data? Is your data widely dispersed, or rather narrowly distributed around some mid point? Are there outliers? What does the overall distribution look like?Summarize your data with descriptive stats50 xpList the poorest and richest countries worldwide100 xpGlobal incomes: Central tendency100 xpDescribe the distribution of your data with quantiles50 xpGlobal incomes: Dispersion100 xpDeciles of the global income distribution100 xpGetting all the statistics50 xpVisualize the distribution of your data50 xpVisualizing international income distribution100 xpGrowth rates in Brazil, China, and the US100 xpHighlighting values in the distribution100 xpSummarize categorical variables50 xpCompanies by sector on all exchanges100 xpTechnology IPOs by year on all exchanges100 xp
