Study Notes
Line Plots
- A line plot is a graph used to count and visualize multiple data points, often used with small groups of numbers.
- Line plots are useful for showing how many times something has happened, such as measuring the length of insects.
Creating a Line Plot
- Start by creating a number line with the unique measurements from the data points (e.g., 1/8, 1/4, 1/6, 1/3, and 1/2).
- Represent each data point as an 'X' above its corresponding measurement on the number line.
Interpreting a Line Plot
- A line plot allows us to easily see the frequency of each measurement, such as how many bugs are a certain length.
Adding Measurements
- To add the measurements of two bugs together, we need to find a common denominator or least common multiple (LCM) if they don't already share one.
- Once we have a common denominator, we can add the fractions together, and simplify the result if possible.
Subtracting Measurements
- To subtract the measurements of two bugs, we need to find a common denominator or least common multiple (LCM) if they don't already share one.
- Once we have a common denominator, we can subtract the fractions, and simplify the result if possible.
