Study Notes
Types of Data
- There are two main types of data: Quantitative and Qualitative.
- Quantitative data is numerical, while Qualitative data is descriptive.
Quantitative Data
- Described as numerical data.
- Can be measured and analyzed using mathematical techniques.
Qualitative Data
- Typically descriptive, providing insights into attitudes, opinions, and behaviors.
- Non-numerical, and often collected through surveys, interviews, or observations.
Converting Data
- Converting data from one form to another is essential for better analysis.
- Examples of data conversion include changing text data into numerical codes.
Descriptive Statistics
- Used to summarize and describe data, providing an overview of the main features.
- Help to understand the characteristics of a dataset.
Inferential Statistics
- Used to make predictions about a population based on a sample.
- Enable researchers to draw conclusions about a larger population.
Data Description
- When describing data, it's important to consider the data collection method, data source, and data description techniques.
- Randomness of data is not a crucial aspect to consider.
Measures of Central Tendency
- The mean is a measure of central tendency that describes the average value of a dataset.
- Also known as the average.
- Other measures of central tendency include the median, mode, and range.
