What is a plot?

Boxing or Box and Whisker Schemes is a method for organizing numerical data along a single numeric line that can be horizontal or vertical. The real fields, when the chart is horizontal, sits slightly above the number and consists of three vertical lines connected together by horizontal lines. The horizontal boundaries of the box are the first and third quartiles (25 and 75. Percentiles) separated by the middle line, which is the middle or 50. On both sides of the box from the center of the horizontal lines, the vertical lines, sometimes called beard, are extended. When they reach the minimum and maximum number of data sets, they end with smaller horizontal lines, although it may differ slightly depending on the data distribution.

There are several important elements that make up a good plot of the box, and some numbers that people need to know when they create these charts. The first is called a summary of five numbers, often shortened and five Num. sum. This is a list of first and third quartiles, median and minimaland the maximum number of data. In some applications, people will have to mention them near the land, although the graph analysis with a good number can also derive these numbers by looking at three horizontal lines and end beard. It is not a question of chicken/eggs for a person who draws the land because five Num. sum. must be used to create a plot.

People must also know the number called Interkvartile Range (IQR). Since the third quarter, the deduction of the first quartile derives IQR and the use of various software or scientific calculators can also obtain this number and summary of five numbers by entering all data. IQR is important because rows ranging from the box usually reach only 1.5 times the IQR. The data outside this point is marked with dots instead of a continuous. These dots often indicate that data has secluded values.

There are many uses for the land. Several charts can be drawn ond with one number A can compare similar sets of data differentiated according to an important factor. For example, scientists or statistics may record the heart rate of men and women and then create two pleated land to seek significant differences in reach and quartiles.

The

box graphs are not solved by the data frequency. Lack of additional scale (vertical or horizontal) omits information about repeated numbers, file size and most individual numbers. A person who looks at the conspiracy is most understood by a summary of five numbers, range and whether data has some remote values. The size of the box, the relationship between the median to the quartiles and the length of the beard can show whether the data is beveled but cannot speak to things like medium, mode or standard deviation. Other graphs, such as histograms, may be more useful when people want to represent things like or deduce better visual effects about data distribution.
