alleryStart learning →The curve used to draw a continuous probability distribution is called the:
AResidual scatter diagram
BProbability density function
CCumulative frequency table
DSample correlation matrix
Answer & Solution
Correct answer: B. Probability density function
1. The curve itself has a formal name.
2. The symbol f of x represents the curve.
3. The curve is called the probability density function, abbreviated pdf.
4. The density function is used to draw the graph of the probability distribution.
