 I am used to display small sets of data.

 I look like a number line.

 I have dots that mark each data point.

 I am measured.

 I am collected.

 I am used to create numeric displays.

 I can be used to display large quantities of data.

 I use ranges instead of exact values.

 My bars have to touch.

 I am in this class right now.

 I am someone who understands how to make a line plot.

 I am someone who can identify types of displays.

Standard(s) MAFS.6.SP Display numerical data in plots on a number line, including dot plots, histograms, and box plots. (Box plots will be assessed with the next lesson) 4 I can create, read and interpret numerical displays of data including  Dot plots  Histograms  Box plots 3 I can create accurate numerical data displays given a set of data.  Dot plots  Histograms 2 I understand what makes a question a statistical question. (MAFS.6.SP.1.1) I can create accurate numerical data displays with the use of my notes/handouts with minimal assistance from my peers and/or teacher. 1 I can identify the type of numerical data display.  Dot plots  Histograms  Box plots I can explain how to create a line plot for a given set of data. (MAFS.5.MD.2.2)

 Your goal is to be able to connect what you already know about statistics to new ways of displaying data.  By the end of this lesson you should be comfortable creating dot plot displays and histograms.  You should also be able to decide which display to use if you are given a set of data.

 I am used to display numeric data  I show each individual data point  I am generally used to show small sets of data.  Why do you think that I am used with small sets of data instead of large sets of data?  Is it impossible to use a dot plot for a large set of data?

Number of pets per student.

 Step 1 : Organize your data  Step 2: Draw a horizontal line  Step 3 : Title your display  Step 4: Label your line with each value smallest to largest  Step 5: Plot your dots

 You can organize data in different ways.  Put all of the data in order least to greatest. ▪ becomes ->  Create a frequency table 2I 3I 4I 5II 6I 7I

 It is important to look at your values so that you draw your line with enough room to put a dot for every occurrence in a data set.  If this is your paper the line near the middle represents a horizontal line.

 Look at your data. The title should tell what data was collected.  Examples  Number of siblings  Number of pets

 Label your line with each value smallest to largest (evenly space your values)

 Make a dot above the value for each time the value occurs in your data

 Rule 1: Every data point must be shown  Rule 2: Horizontal line must be labeled  Rule 3: Labels must be evenly spaced  Rule 4: Dots should be uniform (same size, shape and distance apart)

 I am used to display numeric data.  I use ranges to display data.  I am used to display large sets of continuous data.  How is a histogram different from a dot plot?  Why do you think a histogram used ranges to display data instead of each individual data point?  What do you think the phrase continuous data means?

≤ ≤≤ ≤ ≤ Number of sodas a student drinks in a month.

 Step 1 : Organize your data  Step 2: Draw your perpendicular lines  Step 3 : Title your display  Step 4: Label your lines  Step 5: Draw your bars.

 You can organize data in different ways.  Put all of the data in order least to greatest. ▪ becomes ->  Create a frequency table 2I 3I 4I 5II 6I 7I

 Look at your data. The title should tell what data was collected.  Examples  Height of all 7 th graders to the nearest quarter inch.  Length of every G rated movie that came out after 2005.

 Rule 1 : Bars must touch  Rule 2: Bars must be the same width.  Rule 3: Both axis’ should be labeled.  Rule 4: Axis’ labels must be evenly spaced.  Rule 5: You must title your display.
