A basic box plot. The line in the middle is the median value of the data. Median is used over the mean since it is more robust to outlier values. The first quartile is essentially the 25th percentile; i.e 25% of the points in the data fall below that value. The third quartile is the 75th percentile; i.e 75% of the points in the data fall below that value. Over the years, I've learned that STATA is a powerful data analysis software (data management, graphs and statistics): >>> If you are an undergraduate or graduate student, you may know what quantitative analysis you need, but you may experience difficulties using STATA to get those results, making your research harder. Use Stata value labels to create factors? (version 6.0 or later). # convert.underscore. Convert "_" in Stata variable names to "." in R names? # warn.missing.labels. Warn if a variable is specified with value labels and those value labels are not present in the file. Data to Stata write.dta(mydata, file = "test.dta") # Direct export to Stata In general, this data is very clean and very comprehensive. FBI Crime Data: The FBI crime data is fascinating and one of the most interesting data sets on this list. If you’re interested in analyzing time series data, you can use it to chart changes in crime rates at the national level over a 20-year period. This article continues the series on quantitative trading, which started with the Beginner's Guide and Strategy Identification.Both of these longer, more involved articles have been very popular so I'll continue in this vein and provide detail on the topic of strategy backtesting..
