April  16 Statistical Questions Activity.notebook April 16, 2018
Students will work with their classmates to gather data to find the measures of center and variation, and organize the data in different ways to represent the collected information.
6.SP.1
Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers.
6.SP.2
Understand that a set of data collected to answer a statistical question has a distribution , which can be described by its center, spread, and overall shape.
6.SP.3
Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
6.SP.4
Display numerical data in plots on a number line, including dot plots, histograms, and box plots. 6.SP.5
Summarize numerical data sets in relation to their context, such as by: a. Reporting the number of observations. b. Describing the nature of the attribute under investigation, including how it was measured and its units of measurement. c. Giving
quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in
which the data were gathered. d. Relating the choice of measures of center and variability to the shape of the data distribution and the context in which the data were gathered.

Statistics IB Unit Assessment
• Calculate the mean, mode, median, and range for your data. Your answers will be only for your question. This is done independently. Please show all work!
Today you will start your Statistics IB Unit assessment. The first part is to use your statistical question to survey your class. This research will then be used to find the measures of center.
• If you finish this part early, you may continue on to the representations that need to be completed by Wednesday.
Conceptual Question: As a society, why do we collect so much data?
April  16 Statistical Questions Activity.notebook April 16, 2018
