Explaining data to someone else

Mediation means passing information to another person in a form they can use. Read the table, check the numbers, and say only what the listener needs. Watch out for yearly versus one-time costs.

Data

Survey results

Table: Early survey of 400 Riverside students (fictional data)

Relay task

Rubric | B1

Selects only the relevant information for the listener (B1 mediation).
Numbers are accurate and simplified (first, close behind).
Adds one key explanation (yearly vs one-time cost).
Short, clear notes rather than copied sentences.

פתרונות

הצגת פתרון מלא

Model answer (one possible answer, not the only correct one):

Notes: 400 students answered. Café first, 152 students (38%). Bike lanes close behind, 136 (34%). Skatepark third, 112 (28%). The café is ahead, but by only 4%, so the result is not clear yet. Also important: the café costs money every year, the other two are paid once.

תשובות לתרגול

136
1. Correct answer: 136.
2. Read the row 'Bike lanes': 136 students. 400 is the total number of respondents.
28%
1. Correct answer: 28%.
2. 112 out of 400 students = 0.28 = 28%. 72% would be everyone who did NOT choose it.
The café was chosen by fewer than half of the students
1. Correct answer: The café was chosen by fewer than half of the students.
2. 38% chose the café: the largest share, but less than half (50%), so 'most students' is wrong.
Café (one year) + skatepark
1. Correct answer: Café (one year) + skatepark.
2. ₪60,000 + ₪90,000 = ₪150,000, exactly the budget. Any pair with the bike lanes (₪150,000 alone) exceeds it.
The early lead is small, and new cost information could change the options
1. Correct answer: The early lead is small, and new cost information could change the options.
2. The table shows a 4-point gap (38% vs 34%); in the transcript Noa brings new cost information (₪40,000) that creates a new option. The final vote has not happened yet.
Because the café's cost is yearly and continues, while the lanes are paid once
1. Correct answer: Because the café's cost is yearly and continues, while the lanes are paid once.
2. ₪60,000 per year is ongoing; after 2.5 years it equals the lanes' one-time ₪150,000. Comparing yearly and one-time costs requires explaining the time frame.
