Where are Information Links stored?
Information links are predefined database queries, specifying the columns to be loaded into the internal data engine of TIBCO Spotfire, and any filters needed to reduce the size of the data table prior to visualization1.Information links are created and saved in the library on the Spotfire Server, where they can be accessed by other users2.Information links are not stored on the local machine, as they are not files or settings, but rather structured requests for data2.Reference:

A box plot can visualize which three of the following statistical measures?
Choose 3 answers
A box plot is a graphical tool to visualize key statistical measures, such as median, mean and quartiles1. The median is the middle value of the data, which divides the data into two equal halves. The variance is a measure of how spread out the data is, calculated as the average squared deviation from the mean. The standard deviation is the square root of the variance, which has the same unit as the data.A box plot can show these three measures by using the following elements2:
The band in the middle of the box indicates the median.
The bottom and top of the box indicate the first and third quartiles, which are the medians of the lower and upper halves of the data. The difference between the third and first quartiles is called the interquartile range (IQR), which is a measure of variability similar to the standard deviation.
The bottom and top of the whiskers represent the minimum and maximum values within 1.5 times the IQR from the first and third quartiles. Any values outside this range are considered outliers and are shown as individual points. The length of the whiskers is related to the variance of the data, as larger variance implies more spread out data and longer whiskers.
The mean is denoted by a small circle, which may or may not be inside the box depending on how skewed the data is. The mean is another measure of central tendency, which is the average value of the data. The distance between the mean and the median reflects the symmetry of the data distribution.

Which visualization type can display dynamic items such as sparklines or calculated columns?
A graphical table is a visualization type that can display dynamic items such as sparklines or calculated columns. Sparklines are small line charts that show the trend of a value over time, and calculated columns are expressions that create new data based on existing data. A graphical table can include sparklines or calculated columns as separate columns, along with other columns that show values, icons, or images.A graphical table can also be filtered, sorted, grouped, or aggregated by different criteria12.Reference:Graphical Table,How to Use Sparklines
Which language are action control scripts written in?
Action control scripts are written in IronPython, which is an implementation of the Python programming language that runs on the .NET Framework.IronPython allows you to access the Spotfire API and create custom actions or tools for your analysis1.You can add action control scripts to a text area and link them to buttons, links, or images2.You can also use JavaScript in HTML mode to add interactivity to your text area3.Reference:

Which statistical engine is TIBCO Spotfire Statistical Services NOT compatible with?
TIBCO Spotfire Statistical Services is compatible with several statistical engines, such as S-PLUS, TERR, R, SAS, and MATLAB. These engines provide a comprehensive library of statistical and mathematical algorithms that can be used to perform advanced analytics on data.TIBCO Spotfire Statistical Services can be configured to work with these engines, either as a stand-alone server or as part of a Spotfire stack1. However, TIBCO Spotfire Statistical Services is not compatible with Scala, which is a general-purpose programming language that runs on the Java Virtual Machine.Scala is not a statistical engine, and it does not have a direct integration with TIBCO Spotfire Statistical Services2.Reference:
