The effect of various concentrations of salt solutions on leaf surface and edge browning‚ texture‚ and colour were observed for five days. The experiment was laid out in a Complete Randomized Design (CRD) and each treatment repeated in triplicates including a control. Sensory qualities were examined by six panelists using a 5-point hedonic scale ranking. Results indicated that at brine concentration of 20% and 25%‚ quality parameters

variables (Sower 2010). An experimental design that I think will assist the process engineers in determining what actions to take to reduce laminate thickness variation is the Full-Factorial Design. There are multiple factors to be considered when trying to reduce the laminate thickness variation. A full-factorial allows for all possible combinations of the factors in an experiment at a number of levels to be tested. It allows for the estimation of all main effects and all interaction effects

b. Random Vs. non-random sample 1. Convenience‚ strictly voluntary sampling selection (usually non-random) may have bias in representativeness. 2. Bias in sampling selection means those chosen to participate may differ from those not chosen. A randomized sample reduces bias in sampling selection. NOTE: Many nursing primary references are based on non-random convenience samples! Bias may be reduced through certain data analysis techniques‚ and addressed in design limittions. 3. Methods a. Data
