StatPlus offers support for a wide range of statistical utilities so be prepared to spend some of your time discovering them. You can print the information, send it via email or export it to the same file formats as the input ones. Each cell can be customized in terms of layout (like horizontal or vertical alignment), color, font and border. What’s more, you can insert cells, charts, symbols, functions, comments, pictures, and hyperlinks. A spell checker is included in the package. Editing functionsĮditing features are implemented for helping you activate clipboard-related tasks (cut, copy, paste), delete entries, search for items, and undo or redo your actions. Thanks to the multi-tabbed layout, you can work with different tabs at the same time and quickly switch between them. StatPlus reveals a well-structured GUI where you can input data directly into a spreadsheet or import it from HTML, XLS, CSV, SAV, ODS, or other file formats. It also provides support for an Excel add-in that allows you to carry out statistical tasks directly from Excel’s interface. The app comes packed with a multitude of charts (histograms, bars, areas, point-graphs, pies, statistics, control charts) and worksheet math, statistical and financial functions. 35).StatPlus is an advanced statistical analysis program whose purpose is to help you perform from data transformation and sampling to complex non-parametric and regression analysis, survival analysis, as well as other functions. 005), but there isn’t an interaction between field and variety (p-value =. there is a significant difference between the 4 treatments (p-value =. We see that the cotton variety affects yield, i.e. The results from the Two Factor ANOVA with Replications data analysis tool are shown on the right side of Figure 2 where Rows has been replaced by Block and Columns by Variety. The data can be reformatted for use by the Two Factor ANOVA with Replications data analysis tool, as shown on the left side of Figure 2. Each variety is randomly applied to two plots in each block as shown in Figure 1, which also shows the yield from each plot.ĭetermine whether the cotton variety affects yield and whether there is an interaction between field and variety. The confounding factors (soil quality, water, etc.) are fairly uniform within a field, although they may be different among the fields. Field 1 is located near a river, field 4 is near a road and the other two fields are between them. The land is divided into four rectangular fields (the blocks).
In a similar manner, RCBD with replication is equivalent to two-factor ANOVA with replication.Įxample 1: An agronomist wants to compare the yields of three varieties of cotton. Essentially, RCBD (without replications), as described in Randomized Complete Block Design is equivalent to two-factor ANOVA without replication where the rows are the block factor and the columns are the treatment factor.
