Small-group project: Make a group of 3–4 students. Choose one scenario to design a custom rating scheme by assigning appropriate weights: (a) shopping experience at a cloth store, (b) travel experience in a bus, (c) tourism experience of a nearby tourist spot, (d) clinic/hospital experience. (i) Discuss and arrive at 4–6 aspects to rate. For each aspect chosen, justify why it matters for an overall experience. (ii) Discuss and decide the relative weights and justify. (iii) Collect or imagine ratings from at least 10 people on a scale of 1–5 (5 being very good). (iv) Compute each individual rating. Compute the overall average across individuals. (v) Make a 100% stacked bar chart using your data. (vi) Write a short note on the observations and inferences, what your rating system captures well and what it misses.

Select key aspects like doctor care, cleanliness and waiting time with assigned weights. Calculate weighted scores for ten respondents, plot proportional shares on a 100% bar and evaluate findings. Class 9 Ganita Manjari Chapter 10 How Quantities Combine Understanding Data solutions
