Determine if your household usage of light bulbs is above or below average.
After making an initial conjecture about how the number of light bulbs in their home compares to the average number of lights, students analyze class data using measures of variance (central tendency and standard deviation). Students then use this mathematical evidence to revisit their initial conjecture and draw a sound mathematical conclusion about the number of light bulbs in their home.
To complete this activity, students would need to understand the concepts of central tendency and standard deviation.
Throughout the activity consider how well students:
