Study Notes
Descriptive Statistics
- Calculating the average height of students represents descriptive statistics, which involves summarizing and presenting data.
Categorical Nominal Variables
- The preference for fruits like 'Apple,' 'Banana,' and 'Orange' represents a categorical nominal variable, as categories are distinct and lack inherent order.
Discrete Quantitative Variables
- The number of cars owned by families is considered a discrete quantitative variable because it represents countable whole numbers, not fractional values.
Inferential Statistics
- Analyzing the relationship between study hours and test scores involves inferential statistics for drawing conclusions and making predictions about a larger population based on sample data.
Pie Chart and Bar Graph
- Visualizing categorical data like eye color is best suited for a pie chart or bar graph to represent proportions of each category.
