Week 2: Analysing NZ Sports Data

Tātari Hākinakina Aotearoa - Sports Statistics Analysis

Duration: 4 lessons (50 minutes each) | Year Level: 8

Deep dive into performance trends, probability, and data visualisation using real New Zealand sports datasets

🏆 Big Question of the Week

"What can NZ sports data tell us about performance trends, and how do we predict future outcomes?"

Whakatōhea: Cultural Context - Sports in Aotearoa

In Māori culture, physical competition (whakataetae) has deep roots - from traditional kī-o-rahi to modern rugby. Sports data tells stories of mana, community pride, and cultural identity. When we analyse All Blacks or Black Caps performance, we're not just looking at numbers - we're examining how Aotearoa represents itself to the world.

🏏 Lesson 2.1: Black Caps vs. All Blacks Data Deep-Dive

Focus: Comparing different types of sports statistics and what they reveal

Starter Activity: Sports Statistics Prediction Game (15 minutes)

Hook: Display these mystery statistics without revealing which team they belong to:

Team Mystery A
  • Win Rate: 77.5% (over last 20 years)
  • Home vs Away: 85% vs 70%
  • Average score differential: +12.3 points
  • Performance vs Australia: 68% win rate
Team Mystery B
  • Win Rate: 45.2% (Test matches, last 10 years)
  • Home vs Away: 52% vs 38%
  • Average runs per innings: 298
  • Performance vs Australia: 31% win rate

Student Challenge: Guess which sports and teams these represent. Discuss what clues the numbers give us.

Main Activity: Data Detective Investigation (25 minutes)

📊 Real Data Analysis: All Blacks Performance 2020-2024
Year Matches Played Wins Losses Win % Points For Points Against
2024 8 6 2 75% 187 142
2023 13 12 1 92% 398 221
2022 14 10 4 71% 362 298
2021 15 12 3 80% 456 312
🔍 Student Analysis Questions:
  1. Trend Analysis: Is All Blacks performance getting better or worse? Calculate the average win rate over these 4 years.
  2. Defence vs Attack: Calculate "points against per game" for each year. Which year had the strongest defence?
  3. Prediction Challenge: Based on this trend, predict their likely win rate for 2025. Show your reasoning.
  4. Cultural Insight: Why might 2022 have been a tougher year? Research what major tournaments happened.
🤔 Think-Pair-Share Routine: "I Notice, I Wonder, It Reminds Me Of..."

Individual (3 min): Students complete each prompt about the All Blacks data

Pair (4 min): Share observations and questions with a partner

Share (3 min): Pairs share one interesting "wonder" question with the class

Plenary: Data Storytelling (10 minutes)

Students write a 3-sentence "data story" about the All Blacks performance using evidence from the table. Must include at least one calculation and one cultural connection.

Example: "The All Blacks won 79.5% of their matches from 2021-2024, showing consistent world-class performance. Their strongest defensive year was 2023 with only 17 points conceded per game, coinciding with their Rugby World Cup preparation. This demonstrates how our national team (rōpū taonga) maintains Aotearoa's sporting mana on the world stage."

📦 Lesson 2.2: Box Plot Mastery with CODAP

Focus: Understanding distributions, quartiles, and outliers using digital tools

Starter: Box Plot Mystery (10 minutes)

Visual Hook: Show three unlabeled box plots representing:

  • All Blacks scores per game (2024)
  • Warriors tries per game (2024 NRL season)
  • Breakers points per game (2024 NBL season)

Students guess which is which based on median, range, and quartile positions.

🖥️ CODAP Digital Investigation: Black Caps Batting Averages (30 minutes)

Dataset: Top 15 Black Caps Batsmen - Career Test Averages

Data includes: Player names, career span, matches played, runs scored, batting average, highest score

Cultural Note: This dataset spans from Martin Donnelly (1937-1949) to current players, showing how cricket has evolved in Aotearoa over generations.

CODAP Investigation Steps:

  1. Import Data: Load Black Caps batting dataset into CODAP
  2. Create Box Plot: Generate box plot of batting averages
  3. Identify Features:
    • Median batting average
    • First quartile (Q1) and third quartile (Q3)
    • Interquartile range (IQR)
    • Any outliers (unusually high/low averages)
  4. Historical Analysis: Colour-code players by era (pre-1980, 1980-2000, 2000+)
  5. Comparison Investigation: Create separate box plots for different eras
🎯 CODAP Challenge Questions:
  1. What is the median batting average for Black Caps players in this dataset?
  2. Which player(s) appear as outliers? Research why they might be exceptional.
  3. Compare the IQR between different eras - has batting consistency improved?
  4. If a new player averages 35 runs per innings, where would they rank?
  5. Cultural Extension: Which era had the most Māori or Pasifika representation?

Mathematical Modelling Challenge (10 minutes)

Scenario: "You're the Black Caps selector. Using the box plot analysis, write selection criteria for choosing batsmen for the next Test series."

Success Criteria:

  • Use specific quartile language (Q1, Q3, median, IQR)
  • Justify why certain averages would/wouldn't make the team
  • Consider factors beyond just average (consistency, recent form)
  • Include one cultural or strategic consideration

🎲 Lesson 2.3: Probability in Sports - Predicting Outcomes

Focus: Using historical data to calculate probabilities and make predictions

Starter: Sports Probability Warm-up (10 minutes)

🏆 "All Blacks vs Australia" Probability Challenge

Historical Data: In their last 20 matches against Australia, the All Blacks have won 14 games.

Quick Questions:

  1. What's the experimental probability of All Blacks winning the next match?
  2. Express this as a fraction, decimal, and percentage
  3. If they play 10 more matches, how many would you expect them to win?

Main Investigation: Multi-Sport Probability Analysis (25 minutes)

🏉 Rugby: All Blacks Home Games

  • Challenge: Calculate probability of winning 2-Test home series
⚽ Football: All Whites World Cup

Qualification History: Rare but memorable appearances

  • World Cup appearances: 2 out of last 6 tournaments
  • Probability: 2/6 = 33.3%
  • Question: How might this change with FIFA expansion?
🧮 Advanced Probability Scenarios

Scenario 1: Rugby World Cup Pool Play

All Blacks face 4 pool opponents with these historical win rates: 85%, 92%, 78%, 89%

Calculate: What's the probability they win all 4 pool games?

Scenario 2: Black Caps Batting Collapse

Based on recent data, there's a 15% chance of being bowled out for under 200 in any innings.

Calculate: What's the probability this happens in neither innings of a Test match?

Scenario 3: Whakatane Weather Impact

Local ground has 30% chance of rain affecting play. If rain occurs, there's 60% chance the match is abandoned.

Calculate: What's the probability of a match being completed?

Cultural Mathematics Connection (15 minutes)

Mātauranga Māori and Probability

Traditional Māori games like kī-o-rahi and tapawai involved strategic thinking about likelihood and risk assessment. Modern sports betting and probability concepts connect to traditional decision-making processes.

Discussion Questions:

  • How might kaitiakitanga (guardianship) principles apply to sports team management?
  • What's the difference between statistical prediction and whakatōhea (intuitive knowledge)?
  • How do All Blacks use both data and traditional team culture (whakapapa) in their success?

📋 Teacher Planning Snapshot

Ngā Whāinga Ako — Learning Intentions

Students will develop statistical investigation skills — tūhuratanga raraunga — through authentic data contexts drawn from Aotearoa New Zealand. Using real datasets about Māori communities, sport, environment, and society, students will learn to question, collect, analyse, and communicate statistical findings with cultural awareness and critical thinking.

Ngā Paearu Angitū — Success Criteria

Differentiation & Inclusion

Scaffold support: Provide pre-structured investigation templates and graph frameworks for entry-level learners. Offer extension tasks requiring students to conduct an independent investigation on a topic of their choice, including a written analysis and critical evaluation of their own statistical process.

ELL / ESOL: Pre-teach statistics vocabulary (mean, median, mode, range, sample, population). Use visual data displays and real-world datasets students can connect to personally. Allow oral explanation of statistical reasoning before written tasks.

Inclusion: Offer calculator and digital tools access to all learners. Neurodiverse learners benefit from structured inquiry cycles, visual data displays, and real-world data that provides motivating authentic context. Ensure graph-reading activities include both visual and tabular formats.

Mātauranga Māori lens: Connect tūhuratanga (statistical inquiry) to traditional Māori practices of observation, pattern recognition, and knowledge-making through careful attention to the natural and social world. Use datasets about Māori communities, land, or environmental trends — with attention to the ethics of data sovereignty (who owns data about Māori communities and how should it be used). The maramataka itself is a sophisticated data system encoding centuries of ecological observation.

Prior knowledge: Best used after foundational number and measurement skills. Builds on Year 7 statistics exposure.
