Basics of controlled experiments

Controlled experiments are tests where researchers change specific things and watch what happens. They help find out how one thing affects another while keeping other factors the same.

Main parts of a controlled experiment

Types of experiments for creators

Creators can use different kinds of controlled experiments:

• A/B testing
• User testing
• Randomized controlled trials

These tests can check things like how people use a product, how much they like content, or how often they buy something.

Advantages of using experiments

Planning your experiment

Planning a controlled experiment involves key steps to ensure good results. Here's how to plan your experiment:

Choosing variables

Pick three types of variables:

Creating a hypothesis

Make a guess about what will happen. It should be:

• Specific
• Measurable
• Testable

Example: "Using Facebook will increase website traffic by 20% compared to Twitter."

Designing test variations

Set up different test groups:

Grouping test subjects

1. Decide how many people to test
2. Choose who to include
3. Put people into groups randomly

Example: Pick random website users and put them in one of the three test groups.

Running the experiment

This section covers the key steps for running a controlled experiment. We'll look at choosing a test design, deciding on size and length, measuring results, and reducing outside factors.

Picking the right test design

Creators can choose from different test designs:

Deciding on sample size and length

To get good results:

• Choose a sample size that's big enough to represent your audience
• Make the test long enough to get useful data, but not too long

Measuring results

Track important numbers to see if your ad works:

Compare these numbers between test groups to find out which ad works best.

Reducing outside influences

To make sure your test is fair:

• Keep things like website content and design the same for all groups
• Put people into test groups randomly

This helps make your results more trustworthy and useful for making decisions.

Understanding experiment results

After running your experiment, you need to make sense of the data you've collected. This helps you draw useful conclusions and make smart choices based on what you've learned.

Key numbers to watch

When looking at your results, focus on these important numbers:

These numbers help you see how well your ads are doing and where you can make them better.

Making sense of the numbers

To understand your results, think about:

• Error range: How much your results might be off by
• Chance vs. real effect: Whether your results happened by accident or because of what you did

Looking at these things helps you understand what your results really mean and make good choices based on them.

Mistakes to avoid

When looking at your results, don't:

• Misunderstand what they mean: Make sure you think about the error range and whether the results happened by chance
• Forget about outside factors: Remember that other things might have affected your results

Using experiments in creative work

Testing content ideas

Content creators can use controlled experiments to test different ideas and see what their audience likes best. This helps them make better content.

By comparing how different versions do, creators can choose what works best and make their content better.

Improving design and user experience

Controlled experiments can also help make websites and apps better to use. Testing different design parts can show what people like and what makes them stay longer or do more on the site.

These tests help creators make smart choices about how their site looks and works.

Developing new products

Controlled experiments can also help when making new products or adding new features. Testing different versions can show what people like best and what they're willing to buy.

Advanced testing methods

Testing multiple variables

Testing multiple variables at once is called multivariate testing. It's different from A/B testing, which only compares two versions.

With multivariate testing, you can check how different parts of your page work together. For example, you might test different headlines, images, and buttons all at the same time.

Here's an example of what you might test:

This kind of test helps you find the best mix of elements for your page.

Always testing

Another good method is to keep testing all the time. This means you're always trying to make your content, design, or user experience better.

For example, you might:

1. Test different email subject lines
2. Then test different page layouts
3. Keep going with new tests

By always testing, you can keep improving your work.

Long-term testing plans

Making long-term plans for your tests is also smart. This means thinking about what you want to test over weeks or months.

A long-term plan might look like this:

Having a plan helps make sure your tests match your big goals.

Ethical issues in creative testing

When testing our work, we need to think about what's right and fair. We must make sure our tests don't hurt or trick people, and that we're open about how we do things.

Protecting participant privacy

When we run tests, we often collect information from people. It's important to keep this information safe and private. Here's what we need to do:

Honest reporting of results

We need to be honest about what our tests show, even if it's not what we hoped for. Here's why:

Keeping creative integrity

When we design and run tests, we need to do what's best for the people who use our work, not just what's best for us. Here's how:

Tools for controlled experiments

This section covers the tools creators can use to run and analyze controlled experiments.

Software for running tests

Here are some tools to help you design and run tests:

These tools help you set up tests and look at the results to make better choices.

Data analysis tools

After your test, you need to understand the data. Here are some tools to help:

These tools help you make sense of your test results and find ways to improve.

Learning resources

If you're new to controlled experiments, here are some ways to learn more:

These resources can help you get better at running tests and understanding the results.
