Measuring Measuring Errors

An important part of statistical analysis, perhaps the most important part, is the identification and quantification of sources of variation. For example, in a t-test the variation between groups is compared with variation within the groups to see if the former can be explained by the latter alone. The main tool for measuring variation is the standard deviation (SD), although it is sometimes us...

Influence of Oviposition Time and Lighting Program on Eggshell Quality

The times of oviposition are affected little by the use of a night lighting program. Egg shell weight is not changed by the time of oviposition. Egg weight, shell percentage and it's color vary according to the time of oviposition. The egg characteristics have not been affected by the use of night lighting. Night lighting reduces the percentage of eggs downgraded, in particular reducing by 37 %...
