Which of the following best describes the primary difference between descriptive and inferential statistics in biostatistics?
30
Descriptive statistics use larger sample sizes
Descriptive statistics summarize data, while inferential statistics make predictions about populations
Inferential statistics only apply to medical research
Inferential statistics are always more accurate than descriptive statistics
Q 2/40
Score 0
In a clinical trial comparing two cancer treatments, researchers find a p-value of 0.03. What is the most appropriate interpretation of this result?
30
The probability that the null hypothesis is true is 3%
The treatments are definitely different with 97% certainty
There is a 3% chance that the difference between treatments is due to chance alone
If the null hypothesis were true, the probability of observing such extreme results or more extreme is 3%
