What is the meaning of scale in data handling?
In simple words, a scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data. Here, the vertical axis (y-axis), shows the number of children and the horizontal axis (x-axis) shows the musical instruments.
