It means that there is only one item of numerical information for each fan.
mode, mean and median
You can use them to describe the central tendency of the data but no more than that.
Middle value when the data are arranged in numerical order is the median.
Can the median and mode be used to describe both categorical data and numerical data
When there are a variety of different numbers numerical data varies. -RJC
One reason I can think of why you might not be able to find the mean of numerical data would be if there were missing data points.
No.
Numerical data is numbers. Non-numerical data is anything else.
It means that there is only one item of numerical information for each fan.
Numerical data is quantitative research
Numerical data is data measured or identified on a numerical scale. Numerical can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms, and graphs.
Numerical data are organized by a graph.
mode, mean and median
Understanding and interpret numerical data
A number that describes numerical data is a Statistic.
