StatPlus Portable comes with support for a wide array of files, such as StatPlus documents, Microsoft Excel files, OpenOffice spreadsheets, HTML documents, text, CSV and SPSS files. Comes well-equipped for a plethora of statistical calculations and methods For example, a ribbon toolbar would make the work environment feel more airy and everything else a bit better organized. Speaking of interface, this utility, with its all-encompassing toolbar, would benefit greatly from a more modern layout. The interface is not what you would call up to date, but it is not bad either, as it provides you with a quick way to access all the functions. Upon first starting the utility, you are met by a streamlined user interface that might remind you a bit of older versions of Microsoft Excel.
Complex application that is a bit let down because of its interface It also means that you can take it with you on any portable storage device and run it on any available computer. The first thing you should know about this application is the fact that it is portable, which means that it does not leave any trace on your computer.
#Statplus histogram software
Either way, you are simply naming the different groups for the data.StatPlus Portable is a powerful piece of software that provides you with a set of efficient tools and a suitable environment for graphical and statistical analysis.
#Statplus histogram code
You can use the country abbreviation, or you can use numbers to code the country name. Country of residence is an example of a nominal variable. With nominal data, the sample is also divided into groups but without any particular ordering. For example, in a survey where you are asked to give your opinion on a scale from “Strongly Disagree” to “Strongly Agree,” your responses are categorical. With categorical data, the sample is often divided into groups and the responses have a specific ordering. Histograms do not make sense for categorical or nominal data since they are measured on a scale with only a few possible values. Categorical or nominal data: use bar charts Some examples of continuous data are:įor all of these examples, a histogram is an appropriate graphical tool to explore the distribution of the data. Histograms make sense for continuous data since they are measured on a scale with many possible values. Histograms and types of data Continuous data: appropriate for histograms With some software, you can explore group differences in a single histogram, as is shown in the figures above. If there is a possibility of groups, you are likely to learn more about the data by creating separate histograms for each group. These graphs help identify an important consideration: whenever you create a histogram, think about whether or not there are groups in your data. However, it is harder to see the overall shape than in the first figure. You can still see the center, spread, and shape of the data. However, some software tools allow you to change the number of bins and bin starting points, which allows you to explore and better understand your data.įigure 2 shows the same data as in Figure 1 but with many more bars. With software, the bins are defined by the program. The bar height then shows the number of people in each decade. For example, to create a histogram for age in years, you might decide on bins by decade (0-10, 11-20, and so on). With equal bins, the height of the bars shows the frequency of data values in each bin. Most of the time, the bins are of equal size. To generate a histogram, the range of data values for each bar must be determined. The bars represent the measured values for each category. The bars represent the number of values occurring within a range specified on the horizontal axis. Histograms do not have gaps between bars. Histograms are used with continuous data, while bar charts are used with categorical or nominal data. The key difference between histograms and bar charts is the type of data that is being plotted. What is the difference between histograms and bar charts?
