According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question there are two big errors that David has made. Firstly, he attributing causes where none have been found, since nothing in his sons behavior suggests that it is from a lack of eating together. Secondly, David failed to distinguish between group results and individual needs, eating together does not solve the individual child's current problem which is what is most likely causing him to act out.

Answer:
Overmier and Seligman have described the phenomenon of learned <u>helplessness</u> as the tendency to feel powerless in the face of events that we can't control.
In 1967, Overmier and Seligman conducted a research, which showed that dogs, once found in an uncontrollable situation such as unavoidable electric shocks, were incapable of escaping a different situation, although there was a possible escape in that situation. The phenomenon of learned helplessness is also commonly experienced by humans who, after repeatedly going through a stressful situation, believe they do not have control over the events. They fail to take any action, even if there is a possible solution.
if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.
