👉 (applied mathematics) A data chart (graphical representation of data) intended to illustrate the relationship between a set (or sets) of numbers (quantities, measurements or indicative numbers) and a reference set, whose elements are indexed to those of the former set(s) and may or may not be numbers.
Alright class, settle down, let’s take a look! Today we're tackling the word “graph,” it’s a really important one. The dictionary gives us quite a mouthful, doesn't it? Let’s break it down piece by piece – like building with blocks! (Pause for emphasis) The dictionary says a 'graph' is basically a data chart , a way to show how things relate. It’s all about visualizing information, you see? Think of it this way: You have numbers, quantities, maybe measurements too - let’s say you’re tracking the height of plants as they grow. You plot those heights over time – that's your graph! (Rhyme Time!) "A graph is a picture, clear and bright, Showing data with all its might!" The dictionary also says it shows "the relationship between a set (or sets) of numbers." That means you’re connecting the numbers to each other. Maybe one number represents the amount of rain, and another represents how many flowers bloom – a graph helps you see if there's a connection! It has a “reference set” too, which are like labels or categories – perhaps days of the week or different types of plants. These labels help us understand what the numbers represent. (Summarize) So, in simple terms, a graph is a visual tool that helps you see how things connect and change. It uses pictures (lines, bars, circles - there are lots of ways!) to show data clearly. Do you have any questions about what we've covered? Let’s discuss!
