The Experiment Research Study: Craik and Tulving (1975) Aim: To investigate depth processing by giving participants s number of tasks requiring different levels of processing and measuring recognition. Participants: Controlled condition (3 males and 3 females) Experimental condition (3 males and 3 females) Independent group design Method: This was a repeated measures design experiment with three conditions. Participants were given a list of 60 words‚ one at a time and were required

Randomized Complete Block Design (RCBD) The design allows the grouping of experimental subjects of heterogeneous characteristics into more or less homogenous groups called blocks. By grouping them based on some identified characteristics‚ the difference that would be observed will be largely due to treatment and not due to their characteristics. Another Description of RCBD: Probably the most used and useful of the experimental designs. Takes advantage of grouping similar experimental units into

DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women. Some previous research

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the
