Statistics and Probability (Time, Tables, & Diagrams) - Week 5: Lesson 1: Frequency Tables & Bar Charts
Key Terms:
survey - to ask (many people) a question or a series of questions in order to gather information about what most people do or think about something (när man undersöker vad folk tycker.)
streck (tally mark) - a way of keeping track of numbers in groups of 5. In surveys, a tally mark represents an answer from one single person.
frekvens (frequence) - how many tally marks a particular category has.
- We record tally marks in a frequency table when we do a survey.
In this lesson, we will be reviewing how to create bar charts from a frequency table and survey. We must use the features as follows:
S-scale
T- title
O- origin
L- labels
A- arrows
R- ruler
