Explanation / Answer
20) type I error: it is rejecting H0 when it is true.
14) Many sets of scores have frequency distributions that are shaped roughly like the a mathematical distribution called the normal distribution. Informally, it is called the "bell shaped curve". In Figure 4 below a normal distribution, the dashed green curve, is superimposed over a frequency distribution of scores. The normal distribution roughly matches the frequency distribution of the scores.
Frequency distribution: A frequency distribution is any arrangement of data that shows the frequency of occurrence of different values of the variable or the frequency of occurrence of values falling within arbitrarily defined ranges of the variable called class intervals.
23) Meta-analysis is the statistical procedure for combining data from multiple studies. When the treatment effect (or effect size) is consistent from one study to the next, meta-analysis can be used to identify this common effect. When the effect varies from one study to the next, meta-analysis may be used to identify the reason for the variation.
25) However, the use of effect size serves a different purpose from that of statistical significance: whilestatistical significance test evaluates the probability of obtaining the sample outcome by chance,effect size ... The null hypothesis would say that there is no difference between the groups and thus the effect size is zero.
