Elementary Stats: Frequency, Distribution and Graphs (Vocab)

What is a bar graph?

• A. A graph that uses lines to connect points plotted for the frequencies at the midpoints of the classes.

• B. A graph that displays the cumulative frequency at each class interval.

• C. A graph that uses bars of different heights to represent categorical data.

• D. An organization of raw data in table form, using classes and frequencies.

When is a categorical frequency distribution used?

• A. When the data are continuous.

• B. When the data are categorical (nominal).

• C. When the range is large and classes of several units in width are needed.

• D. When the sum of the frequencies accumulated up to the upper boundary of a class in a frequency distribution.

How is the class midpoint calculated in a frequency distribution?

• A. By subtracting the lower class boundary from the upper class boundary.

• B. By adding the lower and upper class boundaries and dividing by the number of classes.

• C. By adding the lower and upper class boundaries (or the lower and upper class limits) and dividing by 2.

• D. By taking the square root of the upper class boundary.

What does class width represent in a frequency distribution?

• A. The sum of the frequencies for all classes.

• B. The number of values in a specific class.

• C. The difference between the upper class boundary and the lower class boundary for a class.

• D. The additional decimal place more than the data in class boundaries.

• B. A distribution used when the data are categorical (nominal).

• C. A graph that displays the data by using lines that connect points plotted for the frequencies at the midpoints of the classes.

What does a Pareto Chart use to represent frequencies for a categorical variable?

• Proportions instead of raw data

• Sections or wedges according to the percentage of frequencies

• Vertical bars in descending order

• Part of a data value as the stem and part as the leaf

What is the definition of "Raw Data"?

• A graph that displays data by using vertical bars

• Data collected in original form, before any processing or analysis

• A distribution that uses individual data and has a small range of data

• A graph that represents data that occur over a specific time period

What is an Ogive?

• A graph that represents the cumulative frequencies for the classes in a frequency distribution

• A graph that uses proportions instead of raw data as frequencies

• A graph that is divided into sections or wedges according to the percentage of frequencies

• A graph that displays the data by using vertical bars of various heights

What is the purpose of a Stem and Leaf Plot?

• To represent the frequencies of a distribution with vertical bars

• To represent data that occur over a specific time period

• To use part of a data value as the stem and part of the data value as the leaf to form groups or classes

• To display cumulative frequencies for classes in a distribution

What is the definition of "Upper Class Limit"?

• The lower value of a class in a frequency distribution

• The value where a class starts in a frequency distribution

• The upper value of a class in a frequency distribution that has the same decimal place value as the data

• The value that represents the total sum of all class frequencies
