Walmart Store Sales Using Boxplots

Introduction

Boxplots are also known as box and whisker plots. They are used to show the distribution or spread of data and displaying outliers. Boxplots divide the data into four equal parts - quartiles. Each quartile represents 25% of the data and every quartile has an equal number of observations in it.

Boxplots consist of the following elements:

• the first quartile, Q1 making the lower/left part of the box.
• the third quartile, Q3 making the upper/right part of the box.
• the median, which is a line across the box. The box extends from the first to the third quartile (Q1 and Q3), with a line across that represents the median. Half of the observations are below the median and the other half of the observations are above the median.
• IQR. The range of values between Q1 and Q3 is known as the interquartile range (IQR). It is useful in determining the length of the whiskers and outliers. Observations that fall further than 1.5 x IQR are considered outliers.
• The whiskers are the lines extending from the ends of the box up to the fence. The right/upper whisker extends to the maximum value, and the left/lower whisker extends to the minimum value within 1.5 times of the interquartile range. The whiskers show the spread of the data beyond the quartiles, helping us identify potential extreme values. They are calculated as Q1/Q3 -/+ 1.5 * IQR.

Plotting box plots for all the stores.

ggplot(data = WalmartStores, aes(x = Store, y = Weekly_Sales)) +
  geom_boxplot(varwidth = TRUE, fill = "White", colour = "#3366FF") +
  labs(title = "Walmart Store Sales Distribution", caption = "Source Dataset: Kaggle") +
  theme(plot.title = element_text(hjust = 0.5, size = 15, family = "Courier"))

The stores show different sizes of boxes. The shorter the boxes, the more predictable the sales because they are closer to the median. The longer the boxes, the more unpredictable the sales. The sales have a wider range. You want the box part of the plot to be as close to the desired results as possible. That way, businesses can plan in terms of expansion, experimentation, and adapting to customers’ needs. Outliers below the boxplots are underperforming weeks. Outliers above the boxplots are overperforming weeks.

Filtering to the top ten stores.

TopStores <- WalmartStores %>%

Plotting the box plots for the top stores showing their means.

ggplot(data = TopStoresData, aes(x = Store, y = Weekly_Sales)) +
  geom_jitter(colour= "#3366FF", alpha = 0.3) + #the dots appear behind the box

Most top stores have medians above 1,000,000. The boxes are wider showing many observations range around 800,000 to 2,000,000 in sales. The top stores show many outlier values. I use base R’s boxplot.stats function to see the details of these top stores.

Taking a look at the outlier values.

Extracting the rows that have the outlier values and storing them in a vector. They are stored as indices of the rows. There are 36 outliers.

Extracting the contents of the rows for the outlier rows. Now we can see the dates whether there was a holiday or not. Perhaps the holidays led to extreme sales. The dataset came with information on what week dates made a holiday event:

Plotting the stores with the lowest sales

ggplot(data = LowestStoreSalesData, aes(x = Store, y = Weekly_Sales)) +
  geom_jitter(colour= "#3366FF", alpha = 0.3) + #the dots appear behind the box
  geom_boxplot(varwidth = TRUE, fill = "White", colour = "#3366FF", 
               outlier.colour = "Red") +
  stat_summary(fun= "mean", geom = "point", colour = "steelblue") +
  labs(x = "Store", y = "Weekly Sales", title = "Sales Distribution for the Lowest 10 Stores",
       caption = "Source Dataset: Kaggle") +
  theme(plot.title = element_text(hjust = 0.5, size = 15, family = "Courier"))

Majority of the stores with the lowest sales have smaller compact boxes. These sales do not have a wide range, making them predictable. Also, their medians range from around 250,000 to 500,000 in sales.

Getting some statistics measures using boxplot.stats to compare the top stores and the stores with the lower sales. The boxplot.stats function consist of the following components:

• stats – showing the lower whisker, first quartile, median, third quartile, and upper whisker
• n – showing the number of non-NA observations in the sample
• conf – the lower notch and the upper notch. Notches are used to compare medians between groups
• out – the values of any data points that lie beyond the extreme of the whiskers. both underperforming and overperforming outliers.

The stores with the lowest sales show 7 outliers. The lowest outlier recorded around 850k and the highest at 1.1 million in sales, while the top stores had 36 outliers all above 2 million in sales. The median for the top stores was 1,844,987 while the median for the lowest-performing stores was 407,149.3.

Checking the IQR for top stores and lowest store sales. The IQR function shows the difference between the third quartile and the first quartile. It is where fifty percent of the data lies. The top stores have two times the interquartile range value than the lower-performing stores.

Using the five number statistics function to get some statistic measures. The fivenum function shows the five number summary. The minimum value, Q1, median, Q3, and maximum value. It is similar to the boxplot.stats function but simpler. The fivenum does not include information about outliers and confidence intervals. Also, the first and the last values in the fivenum function is the minimum and maximum values, while the first and last values in the stats of boxplot.stats function is the lower and upper whisker.

Finally, creating a function to create a box plot for a specific store.

SpecificStoreBoxplot <- function(Store){
  SpecificStoreData <- WalmartStores[WalmartStores$Store == Store,]
  ggplot(data = SpecificStoreData, aes(x = Store, y = Weekly_Sales, fill = Holiday_Flag)) +
    geom_jitter(colour = "#3366FF", alpha = 0.3) +
    geom_boxplot(varwidth = TRUE, colour = "#3366FF", outlier.colour = "Red", 
                 outlier.shape = 19) +
    labs(y = "Weekly Sales", title = paste("Boxplot on Weekly Sales for Store", Store)) +
    theme(plot.title = element_text(hjust = 0.5, size = 15, family = "Courier"))
}

Type in the specific store number from 1 to 45 in the brackets, to create a box plot for the store.

Limitations of Boxplots

Even though boxplots are good for showing the distribution of data, they have some limitations:

1. They hide the distribution of your data especially if it is a skewed distribution.
2. Displaying the mean, median, and other statistics on the chart can be overloading the chart.
3. It can be difficult to pick out the exact values that are outliers.

Conclusion

1. There are 45 distinct stores.
2. The top 10 performing stores were stores number: 1, 2, 4, 6, 10, 13, 14, 20, 27, 39.
3. The 10 lowest performing stores were stores number: 3, 5, 16, 29, 30, 33, 36, 37, 38, 44.
4. As a group, the top performing stores and lowest performing stores showed the following statistic values:

Statistic Measure	Top Stores	Bottom Stores
Minimum Value	1,158,698	209,986.2
Maximum Value	3,818,686	1,130,926.8
Median	1,844,987	407,149.3
IQR	414,336	170,453.4
No. of Outliers	36	7
