Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 wo
rds to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B. Refer to Research Study 3.4 above to answer the following question. If Dr. Kang decided against using random assignment, which of the following would be threatened? a. The covariance of the study b. The temporal precedence of the study c. The internal validity of the study d. The external validity of the study e. The construct validity of the study
Explanation: The one that would be threatened by using a random assignment is the internal validity of the study.
Internal validity is defined as the grade in which a study can prove relations between the variables; by using a random assignment, there will be variables that weren't taking into consideration and for instance, the internal validity will be lowered.
The internal validity of a study is the term that refers to the ability of a study to show that it has a practical skill, through how well the results of that study have been established. in other words, this validity refers to a study that presents a good performance, because it was established with a correct design, well-developed variables, well-established results evaluation, among other factors, which show that the study was carried out correctly, so your results can be reliable.
If Dr. Kang decided not to use random assignment, the study's internal validity could be a threat to prove the truth, since we have little information on how the entire study was conducted.
The problem is the simple fact that the less fortunate are denied access to school and education while the few others are previlaged and able to have accsess to education. This causes a problem statiing you can only get education if you have the means to afford, accomadate and sustain it. Ex Job instead of home work, etc. Solving this issue would be very difficault but offering some tyoe of extra support to the ones struggling would be the only way. Hope this helps
Sociological affinity refers to "spiritual parentage", curiosity, as well as other behavioral common interests. This is distinguished by elevated degrees of friendship through collaboration, also recognized as affinity collectives or groups, typically in similar organizations.
Individuals who believe they connect collectively, both with as well as without legitimate as well as blood relations, and also who identify oneself as kin.
So that the above would be the appropriate answer.
