Answer:A rubric is a grading tool that describes the criteria, or "what counts," for the assignment.  It also describes each of the criteria according to gradations of quality, with descriptions of strong, middling, and problematic student work.  The criteria are listed in the column on the left.  The numbers in the top row indicate quality, with 3 being the best.   The number 0 is something everyone wants to avoid.  Students may use the rubric as a check list to determine if the writing meets the criteria of the assignment.

Calculate the Zscore of $80
gayaneshka [121]
The Z-score (z) is calculated according to the formula: z = (x - μ) / σ

Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.

x = 80, μ = 5, σ = 4

z = (80 - 5) / 4

z = 75 / 4 = 18.7500

Z-score is 18.7500
