Key Idea.
Section 1
Data Reveals Weather Patterns
The temperature in a place can feel different every day. Even with these daily changes, looking at the weather over a whole month reveals a pattern. This helps people understand what the weather is generally like in that location.
To find this pattern, scientists look at a set of temperature data. They find the single lowest temperature and the single highest temperature recorded during that time.
Section 2
Range Describes Temperature Spread
A group of daily high temperatures collected over a month forms a set of data. Looking at all this data together helps scientists find weather patterns for a place.
One important pattern is the range. The range is the spread of temperatures from the lowest daily high to the highest daily high. It describes how much the temperature changed over the whole month, from its coolest day to its warmest day.
Section 3
A Line Plot Reveals Data Patterns
A list of daily temperatures can be long and confusing. Looking at just the numbers makes it hard to understand the weather over a whole month.
A line plot is a tool that organizes these numbers into a picture. Each day's temperature is marked with an "X" above its value on a number line. This picture of the data makes it easy to see a pattern, like the lowest and highest temperatures.
