Analysing online audience feedback for the school panto: can Mr Bowen trust his 4 stars?

You have a worksheet and, between 2, a stimulus sheet with the online feedback form for the panto Sinderela, its results tables, an automatic chart and some comments. Mr Bowen, Head of Drama, says “Nearly 4 stars, and everybody loved the songs!” Before it goes in the newsletter, you check the data: is the form fair, what do the numbers really say, and who answered?

While the register is called: write your name, class and date on your worksheet, then read The form, exactly as it was written on the stimulus sheet.

Starter question: Question 3 asks “How much did you love our amazing songs?” What is wrong with that question?

Your brief: judge the form, do the sums, find out who answered, fix the chart, advise

You will find 3 problems with the form and rewrite Question 3, work out the mean, median, mode, range and a percentage from the star ratings with working shown, compare the people who answered through the family group chat with those who used the programme QR code, explain why the automatic chart misleads and sketch a fair one, then write Mr Bowen a recommendation of 100 to 150 words backed by figures.

Mean, median, mode

Mean: add every value and divide by how many. Median: the middle value when they are in order. Mode: the most common value. Range: highest minus lowest.

Sample bias

When the people who answer are not typical of everyone, so the results lean one way. The cast’s families are not a typical audience.

Personal data

Information that identifies a person: name, address, phone number. Collect only what you really need, and never force people to give it.

17 minutes

Step 1 & Step 2: 3 problems with the form, then total, mean, mode, range, median and percentage

Step 1 (7 min): 3 problems with the questions (which question, what is wrong, how it affects the data), rewrite Question 3 fairly with new options, and say what to do about Question 6. Copy the first row from the board. Step 2 (10 min): use the All responses column of Table 1. Show working for every answer.

Q What is wrong How it affects the data or the people answering
3 Leading: “love our amazing songs” tells people what to think. People are pushed towards a good answer, so the result is not their real opinion.

14 minutes

Step 3 & Step 4: response rate and the 2 group means, then fix the chart

Step 3 (8 min): response rate (60 out of 340, to 1 decimal place), the mean for each group in Table 1 to 2 decimal places, then which group is more likely to show what the whole audience thought, with 2 reasons, and why people at the back may not have answered. Step 4 (6 min): why does Friday’s bar look so much taller, how big is the real difference, sketch a fair chart from 0 to 5 with a ruler, and write an honest headline.

Group Working Mean
Family group chat (41) 110 + 36 + 12 + 6 + 3 = 167; 167 ÷ 41 = 4.073… 4.07

Slide 5 of 7 · Step 5: your recommendation · Drama · Year 9

9 minutes

Step 5: 100 to 150 words to Mr Bowen, on your own

Write your recommendation and count the words. Include all 4 parts.

1. What the data can tell him, with at least 3 figures you worked out today (for example median 4, 70% gave 4 or 5 stars, response rate 17.6%).

2. What the data cannot tell him, and why (who answered, and what Question 3 could never record).

3. One change to the show next year, based on the evidence in the comments.

4. Two changes to the feedback form.

Step 5 on your worksheet · 9 minutes, written alone Figures, not feelings: quote the numbers you calculated

Swap with your partner and check against the success criteria

Tick each criterion your partner’s work meets. Check their recommendation has at least 3 figures and says something the data cannot tell Mr Bowen. Swap back and correct 1 thing.

  • I can spot leading questions, missing answer options and unnecessary personal data in an online form.
  • I can calculate the mean, median, mode and range from a frequency table, and a percentage, showing working.
  • I can explain how the way a link is shared affects who answers and how far the results can be trusted.
  • I can explain why a chart with an axis that does not start at 0 can mislead, and draw a fair one.
  • I can write a recommendation that uses figures accurately and is honest about the limits of the data.

Round the room, then quick-check answers before handing in

Everyone gives 1 figure they calculated and what it shows, nobody repeats one. Then check these answers.

Question Correct answer
Mean, median and mode of the 60 star ratings? Mean 3.88, median 4, mode 5. Total 233 stars, range 4, 70% gave 4 or 5 stars.
Group chat mean against QR code mean, and the response rate? 4.07 against 3.47; the cast’s families rated higher. Only 17.6% of the 340 audience answered.
Why does the chart make Friday look so much better? The axis starts at 3.7, not 0. The real difference is 3.94 − 3.79 = 0.15 stars.
