Wankarani Settlement Dataset 
The data file LIART.TXT contains the mean sherd and lithic densities at Late Intermediate Period village sites with error ranges at the 80%, 95% and 99% confidence levels. Each line represents a Late Intermediate site. There are 7 lines, each with 9 variables separated by commas. The variables are, in the following order:
1  Site number 
2  Mean sherd density (per square meter) 
3  Mean lithic density (per square meter) 
4  Error range at the 80% confidence level for sherd density 
5  Error range at the 80% confidence level for lithic density 
6  Error range at the 95% confidence level for sherd density 
7  Error range at the 95% confidence level for lithic density 
8  Error range at the 99% confidence level for sherd density 
9  Error range at the 99% confidence level for lithic density 
The first line of the file, for example, looks like this:
LJE,5.43,4.93,±1.83,±0.79,±3.56,±1.53,±6.53,±2.81
This indicates that in site LJE, the mean sherd density is 5.43, and the mean lithic density is 4.93. The error ranges at the 80% confidence level are ±1.83 for sherd density and ±0.79 for lithic density; at the 95% confidence level, ±3.56 for sherd density and ±1.53 for lithic density; and at the 99% confidence level, ±6.53 for sherd density and ±2.81 for lithic density.
The last (7th) line of the file is:
RK27,31.83,11,±16.00,±3.02,±29.00,±5.47,±48.10,±9.05
This indicates that in site RK27, the mean sherd density is 31.83, and the mean lithic density is 11. The error ranges at the 80% confidence level are ±16.00 for sherd density and ±3.02 for lithic density; at the 95% confidence level, ±29.00 for sherd density and ±5.47 for lithic density; and at the 99% confidence level, ±48.10 for sherd density and ±9.05 for lithic density.
