Also remember that each manufacturer may utilize the same color for different means. Black sealant is very commonly used in the manufacture of sealants. This just adds more to the confusion. Not that I have empirical evidence of such, but I believe Permatex is most likely the preeminent maker of RTV gasket maker. They have a whole list of other products as well, but the sealants they make do work pretty well. I'll use their colors scheme to describe the differences and when they should be used.
It uses two columns of data to create a histogram -- one for data you want to analyze and one for bin numbers that represent the intervals by which you want to measure the frequency. Make sure you load the Analysis ToolPak to add the Data Analysis command to the Data tab.Then youâll be ready to create a histogram. Hereâs how: On a worksheet, type the input data in one column, adding a label in the first cell if you want. Be sure to use quantitative numeric data, like item amounts or test scores.ake sure you load the Analysis ToolPak to add the Data Analysis command to the Data tab.

The y axis is scaled so that the total area of the histogram bars is 1. In detail, the probability density histogram is created by: Dividing the data into intervals â see Number of Bins in a Histogram. Counting the number of data points in each interval. Dividing the counts by the total number of data points. Dividing that result by the interval width as shown on the x axis, to obtain the height of the bar along the y axis. In a probability density histogram, the larger the numbers on the x axis, the smaller the numbers on the y axis must be to keep the total area at 1. In a relative frequency histogram, the height of each bar represents the proportion of the data (the fraction of all the iterations) in that bar.
