|Topic Review on "Title":
- Quantitative Data – involves variables that can be counted and are usually measured in units
- Categorical Data – involves variables that are recorded as numbers but represent uncountable objects
- Pie charts: indicate the part of the whole that each individual occupies – let’s examine the data from our table.
- Bar charts have an x and y axis. The x-axis indicates the individuals of the table. The y-axis indicates the variables of the table. The height of the bar indicates the frequency in which a variable occurs.
- Histograms are the most common graphs of distributions with one quantitative variable.
- Stem and Leaf Plots are ideal for small data sets.
