Probability density plots for the Laplace distribution. Pierre-Simon Laplace made the first attempt to deduce a rule for the combination of observations from the principles of the theory of probabilities. He represented the law of probability of errors by a curve and deduced a formula for the mean of three observations.

But the ends of the whiskers can represent several possible alternative values, among them: Any data not included between the whiskers should be plotted as an outlier with a dot, small circle, or star, but occasionally this is not done.

Some box plots include an additional character to represent the mean of the data. Rarely, box plots can be presented with no whiskers at all.

Because of this variability, it is appropriate to describe the convention being used for the whiskers and outliers in the caption for the plot. If the data is normally distributedthe locations of the seven marks on the box plot will be equally spaced.

Four box plots, with and without notches and variable width Since the mathematician John W. Tukey introduced this type of visual data display inseveral variations on the traditional box plot have been described.

Variable width box plots illustrate the size of each group whose data is being plotted by making the width of the box proportional to the size of the group. A popular convention is to make the box width proportional to the square root of the size of the group.

Notches are useful in offering a rough guide to significance of difference of medians; if the notches of two boxes do not overlap, this offers evidence of a statistically significant difference between the medians.

However, there is uncertainty about the most appropriate multiplier as this may vary depending on the similarity of the variances of the samples.No. & Date Asked Question # 12/24/ Suppose a sample of farmers is to be selected for estimating the cost of cultivation of maize per hectare.

The history of statistics in the modern sense dates from the midth century, with the term statistics itself coined in in German, although there have been changes to the interpretation of the word over time. The development of statistics is intimately connected on the one hand with the development of sovereign states, particularly European .
