 A graph with bars is an example of what type of graph? A Bar Graph A graph with a circular formation and uses percents to add up to 100% is an example of what graph? A Circle Graph A graph with a line representing whether the data is increasing or decreasing is an example of what graph? A Line Graph A graph with years/dates and a line is called what? A Time Line A plot with dots that may or may not be scattered through out it is an example of what plot? A Scatter Plot A graph that looks like a bar graph but used intervals and years as the x axis is an example of what graph? A Histogram A graph that is based off of the median and the median of the lower and upper halves is called _____and______ plot A Box and Whisker Plot A table that gives a number to the right and a number to the left is an example of what plot? A Stem and Leaf Plot If you have a set of data for example: 2, 5, 9, 1, 12, 8, 9, 10 To organize this information would you make this info from least to greatest or greatest to least? Least to Greatest In a BACK TO BACK stem and leaf plot do you have the main numerals in the middle, to the right, or to the left? In the middle! To find a mean (or average) you must do what? Add up all of the numbers in the data and divide by the number of numbers. Example: a+b+c+d=e divided by 4 Mode means... The MODE (Most) often or occurs most in the set of data Median means.... The MEDIAN is the middle number in a set of data What 5 values do you need in a Box-n-whisker plot? 1. Minimum Value 2. 1st Quartile 3. 2nd Quartile 4. 3rd Quartile 5. Maximum Value Central Tendency: What are the following answers to the graphs/plots? 1. Box-n-whisker Plot 2. Stem and Leaf Plot 1. Median 2. Mode What are the three different relationships that can be shown on a scatter plot? -No Correlation -Positive Correlation -Negative Correlation What is the correlation of a scatter plot that has data all over the plot? No Correlation What is the correlation of a scatter plot that has data typically going away from the Y axis in a northeastern way? Positive Correlation What is the correlation of a scatter plot that has data typically coming near the Y axis in a southwestern way? Negative Correlation Every graphs needs what? -A Title -Labels for the Y & X axis -Consistent Intervals on both Y & X Axis Does a bar graph touch bars with another bar? NO! Does a histogram touch bars with another bar? YES! Does a Circle graph add up to be 110%? NO! 100% Do you connect the lines in a line plot? YES! In time lines do you show dates and years? YES! In a stem and leaf plot do you include numbers that are not in use? NO! On a frequency table do you include every number in the left column or do you include a interval? You include intervals
