One Variable vs. Two Variable Data
One Variable Data One-variable data sets give measures of ONE ATTRIBUTE.
You can recognize one-variable situations when you see: Tally charts Frequency tables Bar graphs Histograms Pictographs Circle graphs
Two Variable Data Two-variable data sets give measures of two attributes for each item in a sample.
You can recognize two-variable situations when you see….. Ordered pairs Scatter plots Two-column tables of values
One OR Two Variable Data? Noah researches annual hours of sunshine in Canadian cities A study compared the length of time children spend playing video games and the time they spend reading
Fill in the blanks…… As population of a city increases, increases. As population of a city increases, decreases. As temperature increases, increases.
LG: I can distinguish between one- and two-variable data sets.
Consider the variables family income and family expenditure. Increase & decrease together Change in one variable is accompanied by change in the.
Why Do We Use Them?. Graphs and charts let us organize data in an easy to read way. They allow us to make quick comparisons. There are many types.
