The list box at the top left of the chart allows you to choose which subsample is displayed in the front.

Interpreting a dynamic histogram (case 2) The computations begin once you have clicked the OK button. We also activate the “Compare to the total sample option” to see the distribution of the data taken all together. We want to compare the samples so we activate the “Compare the subsamples” option.

In the Options tab we set the number of intervals for the histogram to 5. The information telling which operator made the measurement is recorded in column C. In an exploratory phase, we want to visually investigate whether they are different or not. The measures have been recorded by two different operators (0 / 1). In this case, we imagine we have used a technique to make a measurement on a series of products. Setting up the dialog box to create a dynamic histogram (case 2) The second chart allows to see the two samples and the corresponding fitted normal distributions. The list box at the top left of the chart allows you to choose which sample is displayed in the front. Interpreting a dynamic histogram (case 1) In the Options tab we set the number of intervals for the histogram to 5.Īs we think the data should follow a normal distribution, we choose to display a normal distribution curve fitted to the data. Once you've clicked on the button, the dialog box appears. The data have been recorded in two different columns, and the two samples are independent because measures were not taken simultaneously.Īfter opening XLSTAT, select the XLSTAT / Describing data / Histograms command, or click on the corresponding button of the Describing data toolbar (see below). In this case, we imagine we have used two techniques to make a measurement. Setting up the dialog box to create a dynamic histogram (case 1) Data to create a dynamic histogram Case 1 To create a classical histogram with XLSTAT, you can find a tutorial here. This tutorial will show you the two possible ways to create a dynamic histogram in Excel using the XLSTAT software.
