data that is not organized

What is Raw Data?

200

Lists each category of data and the number of occurrences for each category of data

ex) organizing M&Ms based on their color and how frequently that color shows up in my bag

What is Frequency Distribution or Frequency Distribution Table?

300

How do we find Relative Frequency?

(formula)

relative frequency=Frequency/ sum of all frequencys

- Essentially you are finding the percentage of how much your variable appears in your populations

400

If I label my data horizontally or vertically, used rectangles of equal width to represent the frequency or relative frequency of my data. What would I have?

What is a bar graph?

500

How do we find class width?

class width= largest data value-smallest data value/number of classes

Box Plots: What equations do we use to find upper and lower fences? How do we find IQR?

Lower Fence= Q1-1.5(IQR)

IQR= Q3-Q1
