What Graphs are Bivariate Numerical?
What is..
Line Graph and Scatter Plot
Define Joint Frequency
What is..
The #of times a combination 2 conditions happen. Found in the middle of the table.
What is the formula to find the conditional relative frequency of a two-way graph?
What is..
Joint frequency/marginal frequency
Define Margin of Error.
What is...
The maximum expected difference between a sample result and the population parameter it is estimating.
What is the difference between a histogram and a barograph?
What is...
A histogram shows data values in intervals while bargraphs show data in specific categories.

Explain 5 ways a graph could be misleading.
What is...
The graph doesn't have a title, the #s on the scale are not evenly spaced, the graph does not begin at 0 and does not have a break, the size of the bars are not the same, the axis are not labeled.
