This webpage allows you analyse a sociogram. A sociogram consists of a group of items together positive and negative relationships between those items. The various tools provided for analysing a sociogram are:
The program produces a variety of types of graph. The main choice is what to include: you can include just the positive relationships, just the negatives, or both.
The chart consists of each item plotted at the position so that its x-coordinate is the number of (incoming) positive relationships and y-coordinate the number of (incoming) negative relationships.
If you specify group sizes, the program will attempt to fit the items into those groups. The resulting groups are guaranteed to have no negative relationships.
There are two methods for making the groups. The stronger method only adds an item to a group if there is a positive relationship between an existing item and the new item. The weaker method will allow adding an item so long as there are no negative relationships between it and the existing items.
When a grouping is found, it is printed out. Each group within that grouping is analysed and the result of that analysis displayed after the group as a string of three characters that are zeros or ones. The first character answers the question "Does every item have an incoming positive relationship with another in that group?", the second is the same but for outgoing, the third is whether the group is connected (meaning that there is a chain of relationships between any two items in the group).
It can take a long time to go through all the possible groups. The dots indicate that the program is still working. The progress bar indicates the size of the current attempt at grouping: a full progress bar means that it has found a full grouping.
You can specify the data via a form, in a text box, or by uploading a file. You can download the data suitable for uploading again. You can also save the generated graphs or charts.
