What does the Weighted Median do?

• Divides data into two equal halves considering weights

• Identifies the most frequently occurring value

• Normalizes the frequency distribution

• Calculates the average of all data points

Which measure is used to describe the spread of data?

• Mean

What does the term 'Bin Size' refer to in a histogram?

• The total number of data points

• The width of each interval

• The range of data values

• The height of the bars

In a Normalized Frequency Distribution, what is the purpose of normalization?

• To create a histogram

• To adjust the frequencies to sum to one

• To calculate the median

What is the primary characteristic of the Harmonic Mean?

• It is calculated using the mode

• It is the reciprocal of the arithmetic mean

• It is used for rates and ratios

• It is always greater than the arithmetic mean

What does the Cumulative Probability represent in a distribution?
