The Department of Justice and the Federal Bureau of Investigation publish a compilation on crime statistics for the United States in Crime in the United States. The following table provides a frequency distribution for robbery type during a one-year period. $$\begin{array}{|l|c|}\hline \text { Robbery type } & \text { Frequency } \\\hline \text { Street/highway } & 179,296 \\\text { Commercial house } & 60,493 \\\text { Gas or service station } & 11,362 \\\text { Convenience store } & 25,774 \\\text { Residence } & 56,641 \\\text { Bank } & 9,504 \\\text { Miscellaneous } & 70,333 \\\hline\end{array}$$

Key Concepts

Data Interpretation

Data interpretation is the process of making sense of a dataset by analyzing its summarized form, such as a frequency distribution table. This involves understanding the relative significance of the counts, comparing different categories, and drawing conclusions about trends, which is essential for informed decision-making based on statistical evidence.

Descriptive Statistics

Descriptive statistics involve methods for summarizing and describing the main features of a dataset, including measures such as frequency counts, percentages, and central tendencies. A frequency distribution table is a fundamental tool in descriptive statistics for illustrating how data points are distributed across various categories.

Categorical Data

Categorical data refers to variables that represent groups or categories rather than numerical values. In this context, different types of robbery serve as the categories, and each is assigned a frequency representing its occurrence over a given period.

Frequency Distribution

A frequency distribution organizes data into a table that displays the number of times each value or category occurs. This method allows for a clear visualization of the data’s spread and concentration, making it easier to identify patterns and trends within a dataset.
