Grouped Frequency, Histogram, Frequency Polygon Review

When the range of the data is large, the data must be grouped into classes that are more than one unit in width, in what is called _____________.

• Grouped Frequency Distribution Table

• Interval Frequency

• Categorical Frequency Distribution Table

• Relative Frequency Distribution Table

It represents the smallest data value that can be included in the class.

• Upper limit
• Data range
• Class midpoint
• Lower limit

It represents the largest data value that can be included in the class.

• Lower boundary
• Median value
• Class midpoint
• Upper boundary

These are numbers used to separate the classes so that there are no gaps in the frequency distribution.

• Class intervals
• Data ranges
• Frequency classes
• Class boundaries

A value found by dividing the range by the number of classes.

• Class width
• Class interval
• Class limit
• Class range

It indicates the midpoint value of a class in a frequency distribution.

• Class midpoint

• Class median

• Class average

• Class mode

In a frequency distribution, the total number of observations in all classes is known as ____________.

• Total frequency

• Class frequency

• Relative frequency

• Cumulative frequency

What is the primary purpose of grouping data in frequency distribution tables?

• To calculate mean

• To visualize data

• To reduce data complexity

• To find median

Which graph represents cumulative frequencies?

• Histogram

• Frequency Polygon

• Ogive

• Pie Chart

In a histogram, what represents the frequency?

• Height of bars

• Width of bars

• Label on x-axis

• Label on y-axis
