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...
Explain the concept of error and uncertainty as it relates to decision making. 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 ...
The objective of this investigation was to determine the effects of ingesting whole-blenderized watermelon (BWM) on cardiometabolic risk indicators.A randomized, crossover clinical trial design was employed. During an eight-week trial, overweight or obese (BMI ≥ 85th percentile) boys and girls, ...
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...
The frequency distribution is a systematic arrangement technique of graphically representing the number of observations of the given data corresponding to the given intervals. The interval size is defined based on the size of the observed data; ...
(75 – 25 = 50% of the data). You can also use other percentiles to determine the spread of different proportions. For example, the range between the 97.5th percentile and the 2.5th percentile covers 95% of the data. The broader these ranges, the higher the variability in your dataset...

Mean: Mean refers to the average of all the given values. This is the most common average used in statistics and calculated by summing all the values and dividing it by the number of observations. Answer and Explanation:1 Since, only 5%...
