NURS 8004 FINAL 2026 ADVANCED NURSING
ASSESSMENT PAPER AND SOLUTIONS
GRADED A+
◉ Inferential Statistics.
Answer: Used to make predictions or inferences about a population
based on a sample (e.g., hypothesis testing, confidence intervals,
regression).
◉ Independent Variable (IV).
Answer: The variable manipulated or categorized to observe its
effect.
◉ Dependent Variable (DV).
Answer: The outcome or variable being measured.
◉ Discrete Variables.
Answer: Have a finite number of values.
◉ Dichotomous Variables.
Answer: Only two categories (e.g., yes/no, male/female).
,◉ Continuous Variables.
Answer: Can take on an infinite number of values within a range.
◉ Nominal Level of Measurement.
Answer: Categories with no logical order.
◉ Ordinal Level of Measurement.
Answer: Categories with a logical order but unequal intervals.
◉ Interval Level of Measurement.
Answer: Numerical scales with equal intervals; zero does not mean
absence.
◉ Ratio Level of Measurement.
Answer: Same as interval but with a meaningful zero point.
◉ Central Tendency.
Answer: Measures that describe the center of a dataset.
◉ Mean.
Answer: Average of the data.
, ◉ Median.
Answer: Middle value.
◉ Mode.
Answer: Most frequent value.
◉ Dispersion (Variability).
Answer: Describes the spread of data.
◉ Range.
Answer: Difference between highest and lowest values.
◉ Variance.
Answer: Average of the squared differences from the mean.
◉ Standard Deviation.
Answer: Square root of the variance.
◉ Bar Chart.
Answer: Use: Categorical data; Features: Bars represent frequency
or proportion for each category.
