# Dot plot, boxplot, histogram, and scatterplot

## Greetings

I hope this will explain how dot plots, boxplots, histograms, and scatterplots are created in GeoGebra. The first graph is a the dot plot. The list below was created by entering "({4,5,8,8,5,4,3})". GeoGebra assigned the list to l1, you won't have to type "l1" to assign the data to "l1". Next, type dot plot. An applet will appear with "DotPlot", click the "DotPlot". A prompt appears and prompts for a list of data, type "l1" and delete two or three times to remove the other fields in the prompt. Your dot plot will be generated and ordered pairs showing the location of each dot.

## Dot Plot

Which three data items occur the most?

• A
• B
• C

## BoxPlot

The graph below is a graph of the data for the number of hours spent studying during the week. If you like you can adjust the boxplot by pushing the sliders left or right. The "a" slider adjusts the boxplot vertically shifting the boxplot up and down, the "b" slider narrows and widens the boxplot itself.

## BoxPlot

What is the lowest data point

• A
• B

## Histogram

What is the largest data item in the histogram?

Select all that apply
• A
• B
• C

## ScatterPlot

Is the correlation positive, negative, or doesn't exist?
