The problem with repeated measures designs is that they do not account for order effects. For example:
- The fatigue effect - participants get tired/bored and so perform worse over time
- The practice effect - participants becomes more adept at a task over time
It also can be difficult to avoid the participants being aware of demand characteristics. For instance, if they do a spelling test in silence, and then with heavy metal music playing, they might guess what the experimenter is trying to study, and so react accordingly (whether this is a conscious change or not).

Why do wallpaper and fabric designs tend to contain repeated patterns?
Ease of manufacture, and a smooth, continuous look on the wall.
Is repeated measures and related measures the same thing?
Yes, repeated measures and related measures refer to the same concept in statistics. Both terms describe a study design where the same subjects are measured multiple times under different conditions or over time. This approach helps control for individual differences, allowing for more precise comparisons of the effects of treatments or interventions.
What is the difference between an independent measures design and a repeated measures design?
A repeated measures design involves all participants being used for all possible setups. For example, if you were testing how different music genres effected performance on a spelling test, you would give each participant multiple spelling tests for each genre. Independent measures means that different participants are used for the different setups.
What is a Repeated measures design?
A repeated measures design is where the same participants are used in all measures. For instance, say you wanted to find how different music genres effect scores on a spelling test. You would have a participant do a spelling test while listening to one pieces of music. Then you would have them do another test while listening to a different piece of music, and so on.
What is the primary advantage of a repeated-measures design over an independent-measures design?
The primary strengths of the repeated measures design is that it makes an experiment more efficient and helps keep the variability low. This helps to keep the validity of the results higher, while still allowing for smaller than usual subject groups. twas on wikipedia so not so reliable
What is the definition of ergonomics?
Ergonomics is about designing for people to increase their efficiency. The designs should complement their strengths and abilities and minimize the effects of their limitations
Where can I find deck & patio designs online?
You can find free deck and patio designs online at freedeckplans. They even tell you how much the material will be and measures the deck as well and prices it as well
How far can resistance bands stretch and what are the limitations of their elasticity?
Resistance bands can stretch up to several times their original length, depending on the specific band. The limitations of their elasticity are that they can wear out over time with repeated use, losing some of their resistance and elasticity.
What is repeated measures?
The repeated measures design (also known as a within-subjects design) uses the same subjects with every condition of the research, including the control.[1] For instance, repeated measures are collected in a longitudinal study in which change over time is assessed. Other studies compare the same measure under two or more different conditions. For instance, to test the effects of caffeine on cognitive function, a subject's math ability might be tested once after they consume caffeine and another time when they consume a placebo.(Source Reference: - http://en.wikipedia.org/wiki/Repeated_measures )
What are some examples of unachievable designs that we can explore and analyze in a 2-1 discussion?
Some examples of unachievable designs that could be explored and analyzed in a discussion include perpetual motion machines, time machines, and teleportation devices. These designs are often considered impossible due to the laws of physics and the limitations of current technology.
