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.
As students describe how the carbon cycle contributes to the condition of our environment, they gain a better understanding of the cause and effect of human activities on the Earth's systems.
What are the pros and cons of each measure of center? What are the pros and cons of each measure of variability? Students choose measures of center and variability to represent a data set and justify their choices.
What is mean absolute deviation? Students apply their knowledge of mean and absolute value to understand mean absolute deviation. Students collect data about estimating 30 seconds that they will use in the next lesson.
