* Columns correspond to Variables * Rows correspond to individuals * Rows are often called observations or cases * The number of rows is traditionally denoted by n * In the bar chart the height of each bar is proportional to the count (or percent) in each category * In the pie chart the area of each piece is proportional to the percent of individuals in each category * Pareto chart when the categories are sorted by frequency * Pie charts are less useful than bar charts

1. The sociological perspective‚ as a way of thinking about the world‚ includes the sociological imagination from C. Wright Mills‚ the beginner’s mind from Bernard McGrane‚ and the idea of culture shock from anthropology. Explain what all three of these concepts have in common. Response: All three of these concepts have in common are the idea of breaking down social barriers to gain a different perspective on culture people and behaviors. When a person is in a new area where the culture is different
