But sometimes some important questions arise that need more precise answers. Business value sometimes means distinguishi...
It is used to represent descriptive statistics of each variable in a dataset. It represents the minimum, first quartile, median, third quartile, and the maximum values of a variable. #To draw boxplots for disp (Displacement) and hp (Horse Power) boxplot(mtcars[,3:4]) Output: Data Visual...

Its use isn’t limited to statistics either; many kinds of research need quantitative data including correlational, experimental, and descriptive, and these occur across fields. Digitalization (the process of embracing data and associated tools) and the rise of big data have touched all fields of...
We can add descriptive statistics to our plot using the geom_vline() function. This adds a vertical line geometry to the plot. First, we calculate a descriptive statistic, in this case, the mean price, using dplyr's summarize(). price_stats <- home_data |> summarize(mean_price = mean...
Almost all research questions I have encountered since medical school we’re always interested in causality. Even when we’re actually using descriptive statistics to describe something, we never failed to use causal language to “conclude” or “infer” our findings. E.g. We see a positive aso...
The summary function simultaneously calls many of the descriptive functions listed in Table 5-1, and can be very useful when working with large datasets in data frames to present quickly some basic descriptive statistics, as in the ChopAse example: > summary(ChopAse) varietyA timeA a:6 Min....
One of the first functions beginners typically learn is summary(x). As you might guess, it gets summary statistics for the variable x. That’s simple enough. You might guess that to analyze two variables, you would just enter summary(x, y). However, many functions in R, including this ...
