How do you describe distribution in statistics?
When examining the distribution of a quantitative variable, one should describe the overall pattern of the data (shape, center, spread), and any deviations from the pattern (outliers).
How can you describe the shape of a distribution?
The distribution shape of quantitative data can be described as there is a logical order to the values, and the 'low' and 'high' end values on the x-axis of the histogram are able to be identified. The distribution shape of a qualitative data cannot be described as the data are not numeric.
What does it mean to describe the distribution of data?
The distribution of a data set is the shape of the graph when all possible values are plotted on a frequency graph (showing how often they occur). Usually, we are not able to collect all the data for our variable of interest.
What describes the distribution in math?
Distributions, also known as Schwartz distributions or generalized functions, are objects that generalize the classical notion of functions in mathematical analysis. Distributions make it possible to differentiate functions whose derivatives do not exist in the classical sense.
How do you describe the distribution of a graph?
The shape of a distribution is described by its number of peaks and by its possession of symmetry, its tendency to skew, or its uniformity. (Distributions that are skewed have more points plotted on one side of the graph than on the other.) PEAKS: Graphs often display peaks, or local maximums.
How do you describe the distribution of a data box plot?
When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric. When the median is closer to the bottom of the box, and if the whisker is shorter on the lower end of the box, then the distribution is positively skewed (skewed right).

How do you describe the distribution of a histogram?
A histogram is bell-shaped if it resembles a “bell” curve and has one single peak in the middle of the distribution. The most common real-life example of this type of distribution is the normal distribution.
How do you describe data in a box plot?
The median (middle quartile) marks the mid-point of the data and is shown by the line that divides the box into two parts. Half the scores are greater than or equal to this value and half are less. The middle “box” represents the middle 50% of scores for the group.
How do you describe a distribution table?
A frequency distribution table has two columns. The first column lists all the various outcomes that occur in the data, and the second column lists the frequency of each outcome. Putting this kind of data into a table helps make it simpler to understand and analyze.
