Intro to Statistics
Overview
We can use what we know about collecting data to answer statistical questions.
Statistical questions anticipate variability in the data collected, which means that the answers to the question will not all be the same.
For example…
The question How fast did the students in my class run the race? is statistical because you need to collect data in order to answer it AND there is variability in
the data.
| Data Collected ✓ | Variability ✓ |
| each students race time | different finish times |
The question How fast did Frank run the race? is not statistical because it only
has one answer.
| Data Collected ✓ | Variability ✘ |
| Frank’s race time | only one answer – no variability |
