Statistics and probability
CC.6.SP.1 Develop understanding of statistical variability. Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages.
|
How does understanding variability in data help to analyze data? What is an example of a statistical question that might produce variable data?
|
CC.6.SP.2 Develop understanding of statistical variability. 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.
|
What type of graph does the data set represent? How can the median of a data set not be a value of the data set?
|
CC.6.SP.3 Develop understanding of statistical variability. 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.
|
What single number can represent a numerical data set? How does this number relate to the other values in the data set? How can you describe the measure of variation (range) of a numerical data set with a single number?
|
CC.6.SP.4 Summarize and describe distributions. Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
|
What are the two types of plots and graphs? What do they have in common? How are they different?
|
CC.6.SP.5 Summarize and describe distributions. 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 was 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 was gathered. |
What are some ways to record observations as numerical data? Why do we collect and record numerical data?
