Introduction to Summary Statistics
Statistics - correct answer-the collection, evaluation, and interpretation of data.
Statistical Analysis of measurements - correct answer-can help verify the quality of a design
or process
Central Tendency - correct answer-Center of a distribution
Variation - correct answer-Spread o values around center
Distribution - correct answer-Summaru of the frequency of values
Mean - correct answer-sum of the values of a set of data divided by the number of values in
the data set
Mode - correct answer-most frequently occurring value in a set of data
Bimodal Data Set - correct answer-two numbers equal frequency stand out
Multimodal Data Set - correct answer-More than two numbers of equal frequency stand out
Median - correct answer-The value that occurs in the middle of a set of data in numerical
order
Range - correct answer-The difference between the largest and smallest values that occur in
a set of data
Standard Deviation - correct answer-A measure of the spread of data values
Histogram - correct answer-a common data distribution chart that is used to show the
frequency with which specific values, or values within ranges, occur in a set of data.
Why might a engineer use a histogram? - correct answer-to show the variation of a
dimension that exists among a group of parts that are intended to be identical.
class Intervals - correct answer-Large sets of data often divided into a limited number of
groups
the height of each bar in the chart indicates the number of data elements, or frequency of
occurrence within each range. - correct answer-true
