The graphs in this section were pretty easy to me. Most of them but the circle graph I remembered how to do and were simple to make. The circle graph was one of the harder graphs for me to learn. I didn't remember how you made one so it was like I was learning it all over again. Also, there were a lot more steps involved in creating a circle graph than the others so it was harder for me to remember each step.

Categorical Data- Data that represent characteristics of object or individuals in groups such as black and white, or inside and outside.

Numerical Data- Data collected on numerical variables such as difference in distances.

Dot Plots (line plot) provides quick and simple way of organizing data.

                -Outlier: number on a dot plot that is far from the others

                -Cluster: isolated group of points

                -Gap: a large space between data points

                -Mode- data value that occurs most often 

Bar Graph- used to compare numbers of data in grouped categories. Order does not matter. Can be used to make comparisons.

Histogram- used to compare numbers of data items grouped in numerical intervals. Order matters

Stem and Leaf plot- number line is usually vertical and digits are used instead of x’s. Cant also be used to compare two sets of related data.

Circle Graph (pie chart)- categorical data is used: part of a whole. Use a central angle- to find take a percent of circle time 360 degrees.

Pictographs- used to represent tallies of categories. A symbol or an icon is used to represent a quantity of an item. Pictographs have a legend to explain what the symbol represents.
