Ch. 5 Vocab Quiz tomorrow, Test Friday!

Tomorrow we have our chapter 5 vocab quiz! Here's the list of words to study. You can find most of these in the glossaries at the end of chapter 4 and/or chapter 5. Some of them also appear on old quizzes, and they're all in your notes!

• Quantitative Displays
• Categorical Displays
• Center
• Spread
• Measures of Center
• Measures of Spread
• Interquartile Range (IQR) (both a definition, and the formula)
• Range
• Standard Deviation
• Percentile
• Boxplot
• Histogram
• Dotplot
• Stemplot
• Variance (standard deviation, squared)
• Mean
• Median
• Know how to calculate fences to determine if a data value is an outlier
• Skewed left/right
• Symmetric

Also, we have a test Friday! It's a big deal! Here's a breakdown of what's on that...

• The test includes both open ended and 6 multiple choice questions!
• Determine if a variable is quantitative or categorical (ch. 2)
• Reading histograms...(ch. 4)
• Find sample size, median, and describe shape
• Determine if values are outliers (fences!) (ch. 5)
• Calculating probabilities (like our Titanic stamp problem!) (ch. 3)
• Describing distributions:(ch. 4 and 5)
• Shape, outliers, center, spread (know how to describe each!)
• Know the "appropriate summary statistics," depending on shape
• Know how mean/median compare for different shapes (of distributions) (ch. 5)
• Creating histograms (ch. 4)
• Creating boxplots (both with and without the calculator) (ch. 5)
• Comparing distributions (primarily boxplots) (ch. 4 and 5)
• Finding an average of 2 samples (like that hw problem, p. 97, 37f)
• Know how measures of center (mean, median, mode, midrange) and spread (range, standard deviation/variance, IQR) are affected by extreme values (ch. 5)
• Match boxplots/histograms (ch. 4 and 5)
• Reading graphical displays for categorical data (bar graph, relative bar graph) (ch. 3)
