Standard Deviation - Example Five applicants took an IQ test as part of a job application. If the interval of the X- axis is 1, then the histogram is equal to the relative frequency plot. The histogram is another kind of graph that uses bars in its display. The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. This step seeks to predict the outcome or reasoning of the problem. Mark the middle of each class interval with a tick mark, and label it with the middle value represented by the class.

Histograms are like bar charts with 2 key differences:. The x-axis is the horizontal axis and the y-axis is the vertical axis. As we will find out later, taking the median would be a better measure of central tendency in this situation. Up Next. Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. a graphical depiction of continuous data using bars of varying height, similar to a bar graph but with blocks on the x -axis adjoining one another so as to denote their continuous nature.
