Study Notes
Data Types and Statistics
- Data can be categorized into two types: Quantitative and Qualitative.
- Quantitative data is described as Numerical data, which can be measured and analyzed numerically.
- Qualitative data is typically Descriptive, focusing on non-numerical characteristics and attributes.
Data Conversion and Analysis
- Converting data from one form to another is important because it allows for better analysis.
- An example of converting data form is Changing text data into numerical codes.
- Descriptive statistics are used to summarize and describe data, highlighting its main features.
- Inferential statistics are used to make predictions about a population based on a sample.
Data Description and Measures
- When describing data, it's important to consider the data collection method, data source, and data description techniques.
- The mean is a measure that can describe the central tendency of data, and it's also known as the Average.
- Other measures, such as the range, standard deviation, and interquartile range, are also used to describe data.
