Data vs Statistics vs Information

These terms are often used interchangeably, but they are actually very different, as shown in the following table.

Table: Movie Rentals per Month by University Students

DataStatisticsInformation
2, 3, 2, 1, 4, 3, etc. average number of rentals: 2.5 20 university students rent fewer than 5 movies per month
10, 15, 12, 14, 18, etc. average number of rentals: 14 20 university students rent more than 10 movies per month

 

Statistics are generally presentation-ready; Data will need to be manipulated in order for it to be meaningful.

 

What are Statistics?

According to Statistics Canada, statistics refers to "a type of information obtained through mathematical operations on numerical data" (Statistics: Power from Data!).

Examples of statistics include:

  • the median income of people in a city
  • the average number of children per family in a neighbourhood
  • the average temperature over the past week
 

What are Data?

Yes, "data" is plural! (singular form: datum)

According to Statistics Canada, data are "the raw material from which information is obtained" or the "facts or figures from which conclusions can be drawn" (Statistics: Power from Data!)

Examples of data include

  • the individual income levels of every person in a city
  • the actual number of children per family for each family in the neighbourhood
  • the temperature, taken at hourly intervals, during a one-week period
