Making Sense of Data Collections
Imagine you've surveyed 100 students about their favorite subjects. You get responses like: Maths, English, Science, Maths, English, Science, Maths, Science, Science, English... How do you make sense of this long list?
Frequency tables organize data by counting how many times each value appears. Instead of a confusing list, you get: Maths (28), English (35), Science (37). Much clearer!
Practice questions for Frequency Tables
The table below shows the number of books read by students in a month: | Books read | Frequency | |---|---| | 0 | 4 | | 1 | 7 | | 2 | 11 | | 3 | 6 | | 4 | 2 | What is the mode?
Explain why the mean calculated from a grouped frequency table is described as an 'estimate' rather than an exact value.
