Graph our Data

Histograms

Dot Plots

A Dot Plot is a simple plot on a number line where each dot represents a piece of data in the data set.

Statistical vs. Not Statistical

**Looking at the Math:**

Statistics

Histograms

Dot Plots

Using everyone's Dawn, baby shampoo, and any other bubble data you are interested in, build a histogram, dot plot, and box plot of the data found at http://padlet.com/britniepowell/bubbledata

Answers to statistical questions can be

numerical and categorical.

Data can be organized into a table or graph.

*Histograms

*Dot Plots

*Box Plots

Tables and graphs help us analyze data. We can use measures of center, and observe variation in order to draw conclusions.

A statistical question generates a variety of answers over a population. Non-statistical questions are typically those with only one answer.

Histograms show the frequency of continuous data using intervals on the number line. This means that each bar represents a range of data.

A Box Plot shows the distribution in a number line by dividing the data into quartiles.

Steps to Creating a Box Plot

1. Write the data in order from least to greatest.

2. Draw a horizontal number line with equal intervals.

3. Find the median and mark on the number line.

4. Find the median of the upper quartile and mark it on the number line.

5. Find the median of the lower quartile and mark it.

6. Mark the minimum on the number line.

7. Mark the maximum on the number line.

8. Draw a box between the lower quartile and the upper quartile.

9. Draw a "whisker" from the lower quartile to the lower extreme and a "whisker" from the upper quartile to the upper extreme.
