statistics
central tendency
mode
To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.

Median
median
The middle A find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
-
mean
first you add the number then divide the number by how many numbers you added intend to convey, indicate, or refer to signify.

I.Q.R
The interquartile range I.Q.R is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.

Box plots
he box plot is a standardized way of displaying the distribution of data based on the five number summary
-
Histograms
a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
-
Line plot
A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data. Example.
-
range
The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
-
M.A.D
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set.

statistical questions
variability a statistical question is one that results in multiple and varying numerical answers rather than just one single answer. let's look at these questions and see if they are statistical questions. ... the a statistical question no it is not because it is not a number answer and finally.Statistical and non statistical questions. A statistical question is one that can be answered by collecting data and where there will be variability in that data.
