- Be sure to "count by 5's" on your x-axis!
- For the bottom, I need you to write at least 3 sentences describing what the graph shows us about the number of games Gretzky played (context!)
- We will share out and discuss this writing in class!
In addition, tomorrow we have our first vocab quiz! Be ready! Here's a breakdown of what's on it. (The quiz is 8 multiple choice questions).
- Quantitative Variable (a variable that measures some quantity, with units)
- Categorical Variable (a variable that separates data into categories/groups)
- Data (systematically recorded information (numbers/categories), with context)
- Relative (use %'s in the graph!)
- Which statistics are used for quantitative data? (mean, median, range, standard deviation, IQR)
- Which statistic is used for categorical data? (proportion/%)
- Which graphical displays are for categorical data? (pie chart, (relative) bar graph, (relative) frequency table)
- Which graphical displays are for quantitative data? (dotplot, boxplot, histogram, ogive, timeplot, stemplot)
See you all tomorrow for some more calculator and histogram stuff!
Wednesday HW: Histogram Practice
During his 20 seasons in the NHL, Wayne Gretzky scored 50% more points
than anyone who ever played professional hockey. He accomplished this amazing
feat while playing in 280 fewer games than Gordie Howe, the previous record
holder. Here are the number of games Gretzky played during each season:
79, 80, 80, 80, 74, 80, 80, 79, 64, 78, 73, 78, 74, 45, 81, 48, 80, 82,
82, 70
Using intervals (x-scale) of width 5, create a histogram (appropriately
labeled) using the data above.
Describe the
distribution of “number of games played. "Be sure to write neatly, in
complete sentences, and in CONTEXT! (@ least 3 sentences)
