Percentiles work similarly: they divide scores into 100 groups (or percentiles) so that each group contains exactly 1% of all scores (100/100). This means that if you get a score that places you in the 75th percentile for some test, 75% of other people who took that test had lower sco...
Why are the answers different when you do percentile error method and standard error method? What is homogeneity of variance? The prediction error when x = 8 is ___. a. 4 b. 5 c. 6 d. 7. If alpha is assigned the value 0.001, what are we saying about the type I error? Explore...
Frequencies – Counts, percentages, valid and cumulative percentages; central tendency, dispersion, distribution and percentile values. Descriptives – Central tendency, dispersion, distribution and Z scores. Descriptive ratio statistics – Coefficient of dispersion, coefficient...
When you have a skewed distribution, I find that reporting the median with the interquartile range is a particularly good combination. The interquartile range is equivalent to the region between the 75th and 25th percentile (75 – 25 = 50% of the data). You can also use other percentiles ...

Figure 1. Density function of the BN distribution by varying the parameter k (displayed at the top of each chart). It is noteworthy mentioning that transformations derived from the BN(𝑘) distribution may lead to other domains of interest, e.g., the unit domain. For example, let 𝐵...
