Question 1.

Small-group project: Pick at least one of the following. Make groups of 8 to 10. Collect data individually as needed. Put together everyone’s data and do the appropriate analysis and visualisation. Class 7

(a) Our heights vs. our family’s heights: Collect the heights of your family members.

(i) Make a dot plot showing heights of just your family members. Describe its variability and central tendency.

(ii) Make a double-bar graph showing each student’s height next to their family’s mean height.

(iii) Look at everyone’s data and share your observations.

(b) Estimating time : Check the time and close your eyes. Open them when you think 1 minute has passed (no counting). Note down after how m-any seconds you opened your eyes. Collect this data for yourself and for your family members. Repeat this activity to estimate 3 minutes.

(i) Make two dot plots (for 1 minute and 3 minutes) showing estimates of just your family members.

(ii) Mark these on the respective dot plots. Describe its variability and central tendency.

(iii) Make a double bar graph showing each family’s mean 1 minute estimate and mean 3 minute estimate.

(iv) Look at everyone’s data and share your observations.

Solution:

Do as directed in small groups.
