Student instructions sheet

Introduction

This activity requires you to undertake a statistical investigation using a randomly selected sample from a list of countries of the world. First, you will pose two investigative questions. Then you will analyse the sample and form a conclusion for one of your questions.

This activity is to be completed independently.

You will be assessed on the quality of your discussion and reasoning and how well you link this to the context.

Task

Carry out a statistical investigation on the The World at a Glance sample using the statistical enquiry cycle (Problem, Plan, Data, Analysis, Conclusion).

Problem

Pose two investigative questions about countries that can be explored using The World at a Glance dataset. See Student Resource A for a description of the variables.

Your investigative questions must be comparison questions. A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data.

For each question, state the variable you are investigating and the groups you are comparing.

Now choose one of your two questions for investigation using the data found in Student Resource B.

Plan and data

Because the 60 countries in Student Resource B were selected using a random sampling technique, the sample can be considered representative of all the countries in the database.

Analysis

Draw at least two appropriate graphs that show different features of the data in relation to your investigative question.

Give appropriate summary statistics.

Describe features of the distributions comparatively (for example, shape, middle 50%, shift, overlap, spread, unusual or interesting features).

Conclusion

Write a conclusion summarising your findings. The conclusion needs to include an informal inference in response to your investigative question and to be supported with relevant evidence.

Student Resource A: The World at a Glance variables

The table below shows the values for the six variables included in the dataset in Student Resource B.

The variables in the dataset and explanations of how the variables were collected are:

Variable	Explanation
Country	Randomly selected countries
Climate	Tropical countries are hot and around the equator, temperate countries are colder and lie between the tropics and the poles (tropical, temperate)
Level of development	High means developed countries and low means developing countries
TV Sets	The number of households that have television (per 1000 people)
Literacy rate (%)	The percent of the population in that country that can read
Internet use (%)	The percent of the population in that country that use the internet

This data has been collated using the most recently available information, and can be assumed to describe countries during the year 2013.

NCEA level 1 language features

Statistical Investigation

TASK 1: Establishing a focus.

1. Create a mind map showing the different areas and links for the context MARINE LIFE.
2. You need to include both positive and negative effects, impacts and causes.
3. Think about headings such as people, industry, technology, environment.
4. Use key words as headings and then describe as many factors as you can for each.

TASK 2: Creating good questions

• Create a set of 8 questions that you used to investigate these areas.
• Make sure each questions is specific
• Think about how you could measure this question in numbers
• E.g the impact of pollution could be measured by looking at water quality standards, taking samples of the land, mineral content of soil etc
• Check the information on the FFL Website Statistics information

TASK 3: Data collection

1. Choose one question from Task 2
1. Find the difference between  a closed question and an open question
2. Data collection needs to be not just asking closed questions.
3. Create a list of things you can measure that would help provide evidence or information about the chosen question.
4. What other samples could you collect?

Task 4: Plan an investigation  THINK & PLAN

• What information could you collect?
• Samples: Data, environmental samples
• What resources could be useful?
• Who could help? Ask, find, contact and research.
• How will I measure these things?
• What can I experiment with? Test?

If you have time start writing up an investigation process:

• Investigation question
• Hypothesis / prediction
• Data
• Survey
• Scientific testing
• mathematical testing

Multivariate Cycle

Problem

Pose two investigative questions about countries that can be explored using the supplied dataset.

Your investigative questions must be comparison questions. A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data.

For each question, state the variable you are investigating and the groups you are comparing.

Now choose one of your two questions for investigation using the data.

Plan and data

Because the data was selected using a random sampling technique, the sample can be considered representative of the entire population. State the population that the sample has come from.

Analysis

Draw at least two appropriate graphs that show different features of the data in relation to your investigative question.

Give appropriate summary statistics.

Describe features of the distributions comparatively (for example, shape, middle 50%, shift, overlap, spread, unusual or interesting features).

Conclusion

Write a conclusion summarising your findings. The conclusion needs to include an informal inference in response to your investigative question and to be supported with relevant evidence.

The Cove - Reading response material

The Cove Begins in Taiji, Japan, where former dolphin Trainer Ric O'Barry has come to set things right after a long search for redemption.

The Cove is directed by Louie Psihoyos and produced by Paula DuPre Pesmen and Fisher Stevens.  The film is written by Mark Monroe.

This movie sheds light on the gross mistreatment and slaughter of dolphins in a small town in Japan and also looks at how human actions can impact so negatively on our environment.

Work through the study guide HERE

After watching 'The Cove' we can use this visual text as a Reading Response.  See the Ms Flemmings detailed information in the Google slide about how to complete a reading response.

Intro to statistics (PPDAC)

Today we will unpack the PPDAC cycle which is used to investigate a topic using statistics.  A solid statistics investigation will strengthen your understanding and provide evidence for your inquiry into the current state of marine life in New Zealand and allow you to make more accurate predictions for the future.  This will put you in a better position to suggest appropriate action for a sustainable future for generations to come.

I will offer at least two Achievement Standards this year on Statistics.
If you want more information on these click the links provided.
1.10 Multivariate Data
1.11 Bivariate Data

My goal is to combine the Math & Science standards so we do not need to complete as many assessments and can focus on the learning not the testing. 

1. Have a clear understanding of the use of data.  

2. Provide evidence to be used to make decisions in our inquiry.   

3.  Be able to analyse from both a science and mathematical viewpoint

4. Combine Maths & Science standards, first we must know the similarities and differences in the language we use for each subject.

5. To achieve at a Merit & Excellence.   

Start a new document titled Statistics Introduction. (alternatively you can use your exercise book.

What is the PPDAC cycle?

WATCH



TASK 1: CREATE A RANGE OF QUESTION FOR THE PPDAC
P = PROBLEM
The question is very important as it needs to drive your investigation.

Using the "Write my essay" technique POWER SENTENCE you must create at least 8 questions using 12 words.    Try and vary the types of questions you ask by looking at Marine life from different perspectives (viewpoints) Such as People, Environment, Technology, Self, Others, Society, Protection/Conservation, Economic ($), Government, Sustainability


TASK 2: Understanding the key vocab of statistics

(Khan Academy --> Statistics & Probability --> Start from the basics
This section introduces new vocabulary.  If you find some words or tasks difficult be sure to note these down to discuss next lesson.
(Do we need to create a Lolly Jar for new words like last year?)
Complete as many tasks as you can starting with  Identifying individuals, variables . . . . . .
