    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.
