Today’s Big Mission
You are a World Cup data scout. Choose two favorite teams, find 3 players from each team, and use the 6 goal totals to calculate median and mode.
1 Find the numbers
Use the linked goalscorers table to find goal totals.
2 Organize
Put the data in order from least to greatest.
3 Calculate
Use (N + 1) ÷ 2 to find the median position, then find median and mode.
4 Check your steps
Use the check buttons. If something is wrong, you get a hint, not the answer.
Every Work Page
- Collect or copy data.
- Organize the data.
- Find median position.
- Find median.
- Find mode.
- Explain.
Notes + Student Practice
Median is the middle value after numbers are sorted from least to greatest. Mode is the value that appears most often.
Use (N + 1) ÷ 2 to find the median position. You do the work; the checks only tell you if you are on track.
Median Steps
- Organize from least to greatest.
- Count the values. This is N.
- Use (N + 1) ÷ 2.
- Whole number position: use that value.
- .5 position: average the two middle values.
Mode Steps
- Look for repeats.
- Count how many times each value appears.
- The most repeated value is the mode.
- If nothing repeats, write no mode.
Helpful Frames
Median: The median position is ___ because (N + 1) ÷ 2 = ___.
Mode: The mode is ___ because it appears ___ times.
Practice A
Data set: 2, 4, 1, 2, 3
Practice B
Data set: 3, 1, 4, 2, 3, 2
Warm-Up: Odd + Even Step Checks
Practice twice before the research task. Problem 1 has an odd number of values. Problem 2 has an even number of values. For both, organize the data first, then find the median and mode. Checks give hints, not answers.
Warm-Up 1: Odd Number of Values
Data set: 3, 1, 2, 4, 2
Warm-Up 2: Even Number of Values
Data set: 2, 1, 3, 2, 4, 1, 2, 5
Guided Problem: Top Scorers Practice
Use the table, but the goal totals are not in order. Organize the data, then find median and mode.
| Player | Team | World Cup goals |
|---|---|---|
| Kylian Mbappé | France | 12 |
| Miroslav Klose | Germany | 16 |
| Lionel Messi | Argentina | 13 |
| Ronaldo | Brazil | 15 |
| Pelé | Brazil | 12 |
| Just Fontaine | France | 13 |

Number Finder: Find Numbers, Then Check Your Steps
This page does not calculate for you. It only checks the work you type and gives hints.
Step-by-Step
- Choose Team 1 and Team 2.
- Open the recommended link.
- Use Command + F or Ctrl + F.
- Search your team name.
- Copy only the number in the Goals scored column.
- Find exactly 3 players for Team 1 and 3 players for Team 2.

Goals scored
Do not use matches, tournaments, assists, minutes, or notes.
Try It Here First
Enter any 3 goal totals you found. Then organize, find the median position, median, and mode. The checks do not show answers.
Main Activity: Favorite Teams Lab
Pick two teams. Find exactly 3 players from Team 1 and 3 players from Team 2. Then organize all 6 goal totals and calculate median and mode yourself.
Team 1: 3 Players
| Player | Goals scored |
|---|---|
Team 2: 3 Players
| Player | Goals scored |
|---|---|
Organize → Median → Mode
- Write all 6 goal totals in the first box.
- Organize them from least to greatest.
- N should be 6.
- Use (6 + 1) ÷ 2 to find the median position.
- Average the 3rd and 4th values for the median.
- Look for repeats to find the mode.

Extra Practice: Simple Team Wins
No new research. Use the small table below. The wins are not in order, so organize before you calculate. This section does not calculate for you.
Copy These Wins
| Team | Wins |
|---|---|
| Argentina | 4 |
| France | 5 |
| Croatia | 2 |
| Morocco | 3 |
| England | 3 |

Teacher Launch Note
This version adds two warm-up problems: one odd-sized data set and one even-sized data set. Both have step-by-step checks for organizing, N, median position, median, and mode. Checks give hints without revealing answers.
