Welcome to the World of Investigation!

In Individuals and Societies, being a researcher is a bit like being a detective. You don’t just "search for stuff" on the internet; you carefully choose the right tools to find the truth about how people and societies work. This chapter focuses on Criterion B: Investigating, specifically how you collect and record the information you need for your projects.

Don't worry if this seems a bit technical at first! Once you understand the different types of information and how to organize them, you’ll find that your research becomes much easier and way more interesting.

1. Types of Information: Primary vs. Secondary

Before you start collecting, you need to know where your information is coming from. Most researchers divide their "evidence" into two main buckets:

Primary Research (First-hand evidence)

This is information you collect yourself. You are the first person to gather this data! It is "fresh" and specific to your research question.

  • Examples: Interviews you conduct, surveys you send out, or observations you make while visiting a local park.
  • Why use it? It gives you exactly the information you need, and you know exactly how it was collected.

Secondary Research (Second-hand evidence)

This is information that someone else has already collected, analyzed, and published. You are "reusing" their work to help your own investigation.

  • Examples: Textbooks, news articles, websites, historical documents, or data from organizations like the World Bank.
  • Why use it? It saves time and allows you to look at things that happened in the past or in places you can't visit (like a superpower's empire from 200 years ago!).

Quick Tip: For a top-scoring investigation (Levels 7–8), you should try to use a variety of sources. Mixing primary and secondary research shows you are a thorough investigator!

2. Choosing Your Method: Numbers vs. Words

Depending on your research question, you will need different kinds of data. In Individuals and Societies, we use two main types:

Quantitative Data (The "Quantity")

This is information that can be measured and written down with numbers. It helps you find patterns, averages, and trends.

  • Example: Measuring the population density of a city. \( \text{Population Density} = \text{Total Population} / \text{Land Area} \).
  • Example: Counting how many people use a specific trade route in one hour.

Qualitative Data (The "Quality")

This is descriptive information that is usually about words, feelings, and opinions. It helps you understand "why" or "how" people feel about a topic.

  • Example: Interviewing a refugee about their personal experience with human movement and migration.
  • Example: Analyzing the language used in a social protest poster to understand its message.

Did you know? Neither type is "better" than the other. Usually, the best investigations use both to get a full picture of the situation!

3. Common Research Methods

Here are the "tools" you can put in your researcher's toolkit to collect your information:

A. Surveys and Questionnaires

These are great for getting quantitative data from a large group of people quickly. You can ask "Closed Questions" (Yes/No or multiple choice) to get easy-to-graph numbers.

B. Interviews

Interviews are best for qualitative data. By asking "Open Questions" (How? Why? Describe...), you can get deep, detailed stories from individuals. This is perfect when studying Significant Individuals or personal perspectives.

C. Field Observations

This involves going to a location and watching what happens. In geography, you might observe urban morphology (the shape and layout of a city). You might use a "tally sheet" to record how many people are using a public space.

D. Content Analysis

This is when you study existing "content" like newspapers, speeches, or maps. If you are researching Warfare and Peacekeeping, you might analyze peace treaties to see what words are used most often.

Key Takeaway: Always choose the method that best fits your Research Question. (For more on creating questions, see the chapter on Research questions and their relevance).

4. Recording Your Information Effectively

Collecting information is only half the battle. If you don't record it clearly, you will get confused when it’s time to write your report! Here is how to keep things organized:

  • Use Tables: Tables are perfect for keeping data organized. For example, if you are recording measurements and trends in economics, a table keeps your numbers tidy.
  • Digital Note-taking: Use apps or documents to copy-paste links immediately. Never lose a source!
  • Annotate: Don't just save a document; write a quick note to yourself about why it is relevant to your investigation.
  • Audio/Video: If you are doing an interview, record it (with permission!) so you can listen back later and get the quotes exactly right.

Common Mistake to Avoid: Forgetting to write down where you found the information! You must be able to document your sources later for Criterion C. If you find a great fact, save the URL or book title right then and there.

5. Is Your Information "Appropriate and Relevant"?

To get a high grade in Criterion B strand iii, the IB asks that your information be appropriate, varied, and relevant. Ask yourself these three questions:

  1. Is it Relevant? Does this information actually help answer my specific research question? (If you are researching Trade, don't spend hours collecting data on Warfare unless they are directly linked).
  2. Is it Varied? Have I used different types of sources (e.g., a map, a news article, and a data set)?
  3. Is it Appropriate? Is the source reliable and suitable for an academic project?

Quick Review

1. Primary Research is data you collect yourself; Secondary Research is data others have collected.

2. Quantitative Data is about numbers; Qualitative Data is about words and meanings.

3. Variety is Key: Using different methods (like surveys + articles) makes your investigation much stronger.

4. Record as you go: Always keep a clear system for your notes and save your source details immediately.
