Line plots, also known as dot plots, are simple graphs that use marks (like X's or dots) above a number line to show the frequency of data. They're great for quickly visualizing the distribution of a small set of numbers. Each mark represents one observation or data point.
For example, if you're tracking how many hours of sleep students get each night, you could create a line plot. If 3 students slept for 8 hours, you'd put 3 marks above the number 8 on the number line. This makes it easy to see which sleep durations are most common.
Match the term to its definition:
| Term | Definition |
|---|---|
| 1. Frequency | A. A graph using marks above a number line. |
| 2. Data Point | B. A number that represents a measurement or observation. |
| 3. Line Plot | C. How often a value appears in a dataset. |
| 4. Number Line | D. A visual representation of numbers, ordered from least to greatest. |
| 5. Observation | E. Each individual value in a set of data. |
Complete the sentences using the words from the word bank: Distribution, Marks, Data, Number Line, Frequency.
