Data Presentation

A circle that is divided into sections or wedges according to the percentage of frequencies in each category of the distribution.

• Bar Graph

• Pie Chart

• Pareto Chart

• Time Series Graph

It is the most convenient method of organizing data.

• Pie Chart

• Frequency Distribution Table

• Pareto Chart

• Frequency Polygon

It refers to the number that separate each classes

• Class Boundary

• Class Limits

• Class Mark

• Class Interval

It is a graph that represents the cumulative frequencies for the classes in a frequency distribution.

• Frequency Polygon

• Histrogram

• Ogive

• Time Series Graph

The table determines the shape of the appropriate statistical methods used to analyze the data.

• True

• False

Given the frequency distribution table. Determine the class width.

• c=8

• c=9

• c=10

• c=11

What represents the x - axis of the histogram?

• Cumulative Frequencies

• Class Boundaries

• Class Marks

• Class Limits

It is a graph where the frequencies are displayed by the heights of vertical bars, which are arranged in order from highest to lowest.

• Pareto Chart

• Bar Graph

• Time Series Graph

• Histogram

The graph on the left shows what type of distribution?

• Normal Distribution

• Positively Skewed Distribution

• Negatively Skewed Distribution

• Bimodal

Given the frequency distribution table, find the class mark of the class 117 - 125

• 120.5

• 121

• 121.5

• 122
