Which of the following is not true for dot plots?
Before creating a dot plot, lowest and highest values should be identified first |
It is a simple chart that keeps each observation as a dot along horizontal axis |
Repeating occurrences are represented as dots along horizontal axis |
The data itself is kept within the graph so, its value could easily be identified by looking at the graph |
It helps the researcher to quickly order the data |
In order to create a dot plot one needs to identify the lowest and the highest value of the data set first, then a horizontal axis is drawn and scaled so that it covers the lowest and highest values. A dot plot, essentially, is a simple chart where each observation is presented by a dot along the horizontal axis. If there are repeating observations (multiple occurrences), the dots are stacked up vertically. The dot plots will produce a simple graph of data but at the same time the data itself is never lost, you can easily identify the value of any data point in the dot plot. This is the most powerful aspect of the dot plots. It allows the researcher to show the data in a pictorial form without losing the original information/data. It also gives an opportunity to the researcher to quickly order the data.
