,DATA TYPES, FREQUENCY TABLES, GRAPHS (Questions 1-70)
Question 1: A nurse is collecting data on the number of patients seen in the
emergency department over a 24-hour period. What type of data is being
collected?
A) Continuous
B) Discrete
C) Qualitative
D) Ordinal
Correct Answer: B) Discrete
Rationale: The number of patients is countable, finite, and non-negative, making
it discrete data. Discrete data consists of whole numbers or counts.
Question 2: Which type of graph would be best to display the percentage of
patients admitted by diagnosis category?
A) Bar chart
B) Pie chart
C) Histogram
D) Scatter plot
Correct Answer: B) Pie chart
,Rationale: Pie charts are best for displaying categorical data as proportions or
percentages of a whole. The categories represent different diagnosis types.
Question 3: A researcher asks participants to rate their level of satisfaction on a
scale from 1 (Very Dissatisfied) to 5 (Very Satisfied). What type of data is this?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Correct Answer: B) Ordinal
Rationale: Satisfaction ratings have a meaningful order (1 < 2 < 3 < 4 < 5), but the
intervals between ratings are not necessarily equal, making it ordinal data.
Question 4: Temperature measured in degrees Fahrenheit is what type of data?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Correct Answer: C) Interval
, Rationale: Fahrenheit has equal intervals between degrees and an arbitrary zero
point (0°F does not mean no temperature), making it interval data.
Question 5: The number of siblings a person has is what type of data?
A) Continuous
B) Discrete
C) Qualitative
D) Categorical
Correct Answer: B) Discrete
Rationale: Sibling count is a whole number (0, 1, 2, 3...) that is countable and
finite, making it discrete quantitative data.
Question 6: A histogram is used to display:
A) Categorical data
B) Continuous or discrete numerical data distribution
C) The relationship between two variables
D) Proportions of a whole
Correct Answer: B) Continuous or discrete numerical data distribution
