BMAT BMAT Data Analysis & Interpretation 2

Question 1

A frequency histogram shows BMAT scores with most students scoring 55–65 and fewer students at the extremes. What does this distribution shape suggest?

Accepted Answer

Approximately normal distribution

Answer

A bell-shaped histogram with most scores near the center suggests an approximately normal distribution.

Question 2

In a BMAT data set, the interquartile range (IQR) is used to measure what?

Accepted Answer

The spread of the middle 50% of data

Answer

The IQR is the difference between Q3 and Q1, representing the spread of the middle 50% of data.

Question 3

A table shows drug efficacy rates: Drug A=70%, Drug B=65%, Drug C=80%, Drug D=55%. Which drug has an efficacy exactly 25 percentage points above Drug D?

Accepted Answer

Drug C

Answer

Drug D is 55%, and 55 + 25 = 80%, which equals Drug C's efficacy.

Question 4

In interpreting BMAT results, a p-value of 0.03 means:

Accepted Answer

There is a 3% probability of observing results this extreme if the null hypothesis is true

Answer

A p-value represents the probability of obtaining results at least as extreme as observed, assuming the null hypothesis is true.

Question 5

A clinical trial graph shows two treatment lines that intersect at week 6. What does this crossover suggest?

Accepted Answer

One treatment becomes relatively more effective after week 6

Answer

An intersection indicates a crossover effect where the relative performance of the two treatments changes over time.
