EPIC TRAINING COG170 COGITO FUNDAMENTALS DATA
LINAGE ACTUAL EXAM QUESTIONS AND ANSWERS


What causes of concern would we have about a table component with the following threshold settings?

Column Lower Bound Upper Bound Alert

Percent 34 67 Yellow

Percent 0 33 Green

Percent 68 Red

a. Percent thresholds should divide into perfectly equal parts (e.g. 33.33, 66.66)

b. The thresholds do not account for decimal percent values

c. Percent values are unavailable for threshold logic

d. Alerts should always be ordered from lowest to highest severity, or highest to lowest severity -
ANSWER-b. The thresholds do not account for decimal percent values



Whichever summary format the report builder chooses, they will have to specify how the data is
grouped - what does that mean? - ANSWER-Grouping - All summarization formats fundamentally group
data by common characteristics, and then perform summarization functions on all the data which shares
that characteristic.



What is a summarization function? - ANSWER-Once data has been grouped, summarization functions
aggregate the data and define how it should be displayed for each group. Choosing the wrong
summarization function can obfuscate the data.



Define - Summarization Functions - Count - ANSWER-Tells how many non null values there are! Count -
One of the most common summarization functions is count. Counting a column means that for each
group, your summary will show how many rows in the group have a value in that column. Count does
not care what the value is, only that it exists. This means the only rows not counted are those containing
a NULL in the counted column.



Define - Summarization Functions - Count Unique - ANSWER-How many different values! Counting
unique values in a group is very different from performing a simple count. Counting unique values will
display the number of different values stored in a column for each group. NULL values will still not be
counted.

, Define - Summarization Functions - Sum - ANSWER-Adds together - Sum is only used for numeric
columns. It adds up the values in a column for each group. When adding up numbers, neither a 0 nor a
NULL will affect the total sum.



Define - Summarization Functions - Average - ANSWER-Sum divided by Count - Average is also applied to
numeric values and can be thought of as Sum divided by Count. It is important to recognize that since
the denominator of this function is a Count, this means that the number of NULL values will not be
considered when calculating an average.



Define - Summarization Functions - Percentage - ANSWER-A percentage can be thought of as the ratio of
two counts or two sums. One function is the numerator, and one function is the denominator.



For a count-based percentage, it is common for the denominator to be a count of all rows in the
population, with a numerator being the count of all rows in the group. Since both the numerator and
the denominator are counts, no NULLs will be included in either.



For a sum-based percentage, the denominator is usually the sum of all numbers in the data set, while
the numerator is the sum of then numbers in just one group. Since the sum function does not include
NULLs, both the numerator and denominator will ignore them.



There are several common errors made when choosing how to summarize. Follow these

rules. (list three) - ANSWER-• DO NOT use a count function on numeric data to find total amount.

• DO NOT use count unique unless you want to display "number of different values."

• When using an average function, find out if the column stores a NULL or a 0 when no data is entered.



Which Function? choose the correct summarization function(s) you might need. How much money did
we charge in 2011? - ANSWER-Sum



Which Function? choose the correct summarization function(s) you might need. How many patients
were seen in each clinic? - ANSWER-Count Unique
