What is Data?
Data is information, often shown as numbers, that we collect to study, understand, or make decisions
In math, data refers to facts, numbers, or information we gather to answer questions or solve problems. Data can come from counting, measuring, asking questions, or observing things around us, like:
- Recording how many pets each student in a class has
- Measuring daily temperatures
- Collecting scores from a basketball game
We can organize data in tables, charts, and graphs to make it easier to read and understand. Analyzing data helps us find patterns, make predictions, and draw conclusions.
There are two types of data in math:
- Numerical data: Numbers, like ages or test scores
- Categorical data: Labels or groups, like favorite colors or types of fruit
When Do Students Learn About Data?
Students are introduced to data early by collecting and organizing information, then build on these skills to analyze and interpret data in later grades.
Grades 1–2 – Collecting and Sorting Data
Students learn to gather simple data (like favorite colors) and display it in basic charts.
Grades 3–5 – Reading Graphs and Analyzing Data
Students create and read bar graphs, pictographs, and line plots. They begin to answer questions based on data.
Grades 6+ – Working with Advanced Data
Students use data in statistics, probability, and more complex graphing, including histograms and box plots.
