Individual project (long term): This requires collecting data over 2 weeks or more. In and Out: Track how many times you step out of your house in a day. Do this for a month. (i) Describe the variability and central tendency of this data. Make a dot plot. (ii) Do you find anything interesting about this data? Share your observations. (iii) You can ask any of your family members or friends to do this as well.
Project Overview: Students track daily outings for a month, recording the number of times they leave home each day.
(i) Variability and Central Tendency: Create a dot plot showing the distribution. Calculate mean and median. Describe variability (range, clustering). Identify patterns (weekdays vs weekends, weather effects, etc.).
(ii) Interesting Observations: Variation patterns might be noted. Comparisons with family members can be made.
(iii) Family/Friends Participation: Family members or friends can participate for data comparison.
Explanation
This long-term project develops data collection habits and analytical skills. Students learn about variability in daily life data and practice creating visualizations and calculating measures of central tendency.
