Assignment 2

This assignment is based on topics covered in class-12 (Aug 22, Sat) and class-13 (Aug 28, Friday). These topics are related to the design of controlled experiments. For weightage and due date, please refer to the deadlines page.

PART-1 (based on class-12, 2-factor experiment design)
  1. Start with a personal challenge - It could be anxiety led (e.g. not able to manage time, no exercise, job worry,...) or it could be aspiration led (e.g. getting my dream job, building a skill, achieving a goal,...). It could be a combination of both. Write the challenge.
  2. Create a hypothesis about what you can do that might help you overcome the challenge or achieve your goal. It is ok to divide your challenge/goal into sub-challenges/sub-goals and focus on one sub-challenge/sub-goal. You can take help from your friends / Google to generate this hypothesis. It doesn't have to be original. Write the hypothesis.
  3. Identify 2 factors associated with this hypothesis and one measurable outcome. Mention these factors and the outcome. (class-12, slide-16 and 18). If you use an outcome that is difficult to quantify (e.g. taste of a cookie) then use human expertise available to judge it and try to take an average.
  4. Identify low and high values for the 2 factors. Please do some trial-and-error runs to identify low and high values. These values could be numeric (e.g. number of popped corn seeds, time on the stove) or it could non-numeric (e.g. white corn vs yellow corn). Please refer to the pop-corn and cooker whistle experiments from class-12. Mention the low and high values and the trial-and-error you did to arrive at these.
  5. Perform the 4 experiments in random order. Please add a picture of your experimental set-up. If that is difficult, please give some evidence that you performed these experiments. e.g. a picture of the outcome of each experiment whether it is physical (like a cookie) or virtual. 
  6. Write the results in the table with standard order and actual (random) order (class-12 slide 18). 
  7. Draw a cube-plot, write the results, and draw a contour diagram. You can assume the plots to be linear for this experiment. To see how to add contours you can refer to this video (9:21-10:33)
  8. What did you learn from this experiment? Please write briefly (not more than 4 sentences)
PART-2 (based on class-13, A/B testing)
  1. Imagine a mobile app that helps you in this journey to overcome the challenge. Write what this app will do.
  2. Draw a screen of the app. You can use an existing app if you find a suitable one. But the hand-drawn UI screen is just fine. Draw the screen.
  3. Imagine a hypothesis about making one change to the UI such that we get some better outcome. Write the hypothesis.
  4. Design an A/B test that tests this hypothesis.
Please submit a PDF from PowerPoint and the page limit is 7 (5 for part-1 and 2 for part-2). Please give sources (if you have any) at the bottom of the respective slide.
