Explanation

A Quantity Index Number measures changes in the quantity or volume of goods over time or between places.

It focuses on physical amounts, not prices or values.

Explanation

A composite index number combines two or more variables into a single index value.

It's often used to measure overall trends, such as in economics or price levels.

Explanation

IQR measures the spread of the middle 50% of the data.

It is calculated as:

  IQR = Q3 – Q1

Explanation

In a histogram, the Y-axis represents the frequencies (i.e., how many data points fall into each class).

The X-axis shows the class intervals (data ranges).

Explanation

Relative frequency is the ratio of the frequency of a class to the total number of observations.

When you add the relative frequencies of all classes, the total must equal 1 (or 100%).

Explanation

An Ogive is a graph that shows cumulative frequencies, either less than or greater than a certain class limit.

It's used to determine medians, percentiles, and quartiles visually.

Explanation

Class boundaries define the exact limits for grouped data.

For a class centered at 25 inches, a typical class width (e.g. 5.2) gives boundaries like 23.50 to 28.70.

Explanation

A standard normal distribution has:

Mean = 0

Standard deviation = 1

So, Variance = (Standard deviation)² = 1² = 1

Explanation

Blood types are non-numeric categories (A, B, AB, O), with no inherent order, so they are nominal.

Since each individual has only one blood type, the data is counted and presented in a discrete frequency distribution.
