In an experiment, the process of random assignment ensures that each participant has an equal chance of being in either the control group or the experimental group.
Random assignment refers to the use of random methods in psychological experiments to equalize the chances of each participant being assigned to a particular group. Participants in the study will be divided into various groups at random, such as an experimental group or a treatment group.
Tossing a coin, picking a name out of a hat, rolling dice, or giving players random numbers are just a few examples of random assignment techniques. Remember that random assignment is distinct from random selection. Random assignment describes how those chosen participants are then assigned to experimental groups, whereas random selection describes how people are picked at random to represent the greater community.

The Egyptians used a weird method to reduce friction by pouring water onto the sand, causing the sand to clump together and make it easier to pull along due to the reason that each individual piece of sand doesn't hold it back. They called this weird technique capillary bridges.
Answer: This is an example of problem-focused behavior coping.
Explanation: When a problem arises in day-to-day life, irrespective of at work or at home, the behavior tends to change and may bring prolonged sadness. To cope up with this behavior knowing full well that it may cause loss, the problem, not the feelings, needs to be focused in order to find out solid solutions to it. This approach is thus called a problem-focused behavior coping approach.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be: 9:3:3:1.
<h3>What is a phenotype ratio?</h3>
- The phenotypic ratio refers to the proportion of offspring that exhibit a specific trait or set of traits. A test cross can be used to ascertain the frequency of a trait or trait combinations that will manifest themselves based on the genotypes of the progeny.
- The ratio of various phenotypes found in a cross's progeny is known as the phenotypic ratio. Comparisons using numbers are ratios. For instance, the proportion of apples to oranges would be 3:2 if someone had three apples and two oranges.
- We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the expression and appearance of the alleles.
- Phenotypes include things like height, wing length, and hair color. In addition to measurable traits that may be observed and tested in a lab, phenotypes also include blood cell or hormone levels.
