Which of the following best describes 'data normalization'?
Answer: Scaling values to a common range such as 0 to 1
Normalization rescales numeric data to a standard range (commonly 0–1) so variables with different units can be fairly compared.
A table shows that 40 out of 200 surveyed professionals passed an exam. What is the pass rate?
Answer: 20%
The pass rate is 40 ÷ 200 = 0.20, which equals 20%.
Which chart type is best suited for displaying trends over time?
Answer: Line chart
Line charts connect data points in chronological order, making them ideal for visualizing trends and changes over time.
What does the term 'outlier' refer to in data analysis?
Answer: A data point that falls far outside the typical range of the dataset
An outlier is an observation that is significantly different from other data points and may indicate variability, error, or a novel finding.
If a bar chart shows Category A with a value of 80 and Category B with a value of 40, Category A is how many times larger than Category B?
Answer: 2 times
80 ÷ 40 = 2, so Category A is exactly 2 times larger than Category B.
In data interpretation, 'reliability' refers to:
Answer: The consistency of results when the measurement is repeated
Reliability refers to the degree to which a measurement produces stable, consistent results across repeated tests under the same conditions.
