Study Notes
Algebra
- Variables are used in equations to represent unknown numbers.
Statistics
- Central tendency is a measure that describes the typical value of a dataset. The most common measure of central tendency is the mean.
- Standard deviation measures the spread or variability of a dataset.
- A larger standard deviation indicates a dataset with greater variability, meaning the data points are more spread out from the mean.
- Outliers can significantly affect the mean.
- The median is a robust measure of central tendency, meaning it is less affected by outliers than the mean.
- Data analysis involves identifying patterns within data.
- Regression analysis estimates relationships among variables.
- Hypothesis testing determines if there is enough evidence to reject a null hypothesis.
- Normal distribution is symmetrical and bell-shaped.
Geometry
- Geometry focuses on the properties of shapes and their relationships.
- Transformations such as translations, rotations, and reflections are used to manipulate shapes and their positions.
Calculus
- Calculus is used to study the rates of change of functions.
Key Terms
- Variables are symbols that represent unknown numbers in equations.
- Mean is the average of a dataset.
- Standard deviation is a measure of the spread of data points around the mean.
- Median is the middle value in a sorted dataset.
- Outliers are data points that are significantly different from other values in the dataset.
- Data analysis involves identifying patterns in data.
- Regression analysis is a statistical method used to estimate relationships among variables.
- Hypothesis testing is used to determine if there is enough evidence to reject a null hypothesis.
- Normal distribution is a probability distribution with a bell-shaped curve.
- Transformations in geometry are used to manipulate shapes and their positions.
