Question

Range of the data 15, 26, 39, 4, 11, 18,7, a is​

Answer 1

Step-by-step explanation:

Set: 22, 26, 29, 33, 39, 40, 42, 47, 53

In this example, 39 is the median or middle value in the set.

Mode

The mode is basically the most frequent value that repeats itself in a set of values. For instance, if your set has 21, 9, 14, 3, 11, 33, 5, 9, 16, 21, 5, 9, what is the mode?

The answer is 9 because this value is repeated 3 times.

In statistics, mean, median, and mode are all terms used to measure central tendency in a sample data. This is illustrated by the normal distribution graph below.

The normal distribution graph is used to visualize standard deviation in data analysis. Distribution of statistical data shows how frequent the values in a data set occurs.
