If you're an IB student taking IB Maths, the internal assessment (IA) can be a daunting task. However, with the right approach and tools, you can make the process easier and even enjoyable. Here are seven math IA topic ideas that you can use to write an excellent IA and get good marks.
1. Difference of Means Test
A difference of means test is a simple and straightforward statistical method that you can use to compare the average of two sets of data. You can use this test to compare the salary of people who graduated from community college and those who graduated from Ivy League schools, or to compare the popularity of two artists or songs.
2. Linear Regression
Linear regression is a statistical method that helps you to find the relationship between two variables. For example, you can use linear regression to analyze the relationship between a student's height and their grades in school. This method is also useful for analyzing the relationship between a company's sales and advertising expenses.
3. Time Series Analysis
Time series analysis is a method that helps you to analyze data that is collected over time. For example, you can use time series analysis to analyze the trend of a stock's price over a certain period of time, or to study the trend of a country's GDP growth over the past decade.
4. Chi-square Test
The chi-square test is a statistical method that helps you to compare the difference between two sets of data. For example, you can use the chi-square test to compare the popularity of different sports in different countries, or to compare the consumption of different foods in different cities.
5. Anova
Anova is a statistical method that helps you to compare the means of three or more sets of data. For example, you can use Anova to compare the average salary of people in different countries, or to compare the average height of people in different cities.
6. Correlation and Causation
Correlation and causation are two important concepts in statistics that help you to understand the relationship between two variables. For example, you can use correlation and causation to analyze the relationship between a person's age and their salary, or to analyze the relationship between a person's height and their weight.
7. Hypothesis Testing
Hypothesis testing is a statistical method that helps you to test a hypothesis about a population. For example, you can use hypothesis testing to test the hypothesis that a certain group of people is taller than another group, or to test the hypothesis that a certain brand of soap is more effective than another brand.
In conclusion, these are seven ideas that you can use to write your math IA. Remember, the key to writing a successful IA is to choose a method that interests you and spend time learning the theory behind it. Good luck!
