What measure do you use to find the center of a skewed graph? symmetrical? -
ANSWER ✅✅✅✅Skewed: Use *median* to find center
Symmetrical: Use *mean* to find center
What are the 3 classifications of analytics and describe each? - ANSWER
✅✅✅✅Descriptive Analytics:
Describes a situation using techniques like statistics to summarize and describe the
data
Predictive Analytics:
Uses historic data to model and predict potential outcomes of a situation, often
incorporating the use of uncertain variables.
Prescriptive Analytics:
Prescribes a course of action to achieve the best result for a given problem.
What are the (5) steps of the business analytics process? - ANSWER ✅✅✅✅1)
Problem Definition
Begin with a clear definition of the business problem.
2) Data Preparation
Understand both why certain information is gathered, and how that information is being
utilized across departments
3) Technical Analysis and Modeling
,Use both people and technology in the exploration and understanding of the data
through modeling and statistical analysis
4) Evaluation of Results
Evaluate the results in the context of business objectives
5) Deployment
Organize and present the data in a way that benefits the organization.
What is descriptive statistics? - ANSWER ✅✅✅✅A method of summarizing the
characteristics of a single variable within a set of data.
*applies when we have data for a complete population - for all students.
What are the (3) focuses of descriptive statistics? - ANSWER ✅✅✅✅1) Measures of
Shape
2) Measures of Center
3) Measures of Spread
What does skewness indicate about the shape? - ANSWER ✅✅✅✅If skew is less
than −1 or greater than +1, the distribution is skewed.
If skew is between -1 and +1, we will treat the data as symmetrical.
What measure do you use to find the center of a skewed graph? Symmetrical? -
ANSWER ✅✅✅✅Skewed: Use *median* to find center
Symmetrical: Use *mean* to find center
What measure do you use to find the spread of a skewed graph? Symmetrical? -
ANSWER ✅✅✅✅Skewed: Use *quartiles* to find spread
Symmetrical: Use *StDev* to find spread
What is standard deviation? - ANSWER ✅✅✅✅the average distance between each
data point and the mean.
The standard deviation indicates the spread of the data, and therefore the volatility
within the business process.
How does the median, quartiles, percentiles, and five number summary describe the
spread? - ANSWER ✅✅✅✅Median: splits the data into 2
Quartiles: splits the data into 4
Percentiles: splits the data into 100
Five number summary: Minimum, 1st q, 2nd q, 3rd q, maximum
, How do you find outliers with symmetrical data? - ANSWER ✅✅✅✅-find the mean
and stDev.
Lower Limit= ((mean - (2 x stDev))
Upper Limit= ((mean + (2 x stDev))
How do you find outliers with skewed data? - ANSWER ✅✅✅✅-find the *IQR* = (Q3 -
Q1)
Mild Lower Limit = ((Q1 - (1.5 x IQR))
Mild Upper Limit = ((Q3 + (1.5 x IQR))
Extreme Lower Limit = ((Q1 - (3 x IQR))
Extreme Upper Limit = (Q3 + (3 x IQR))
What do skew and correlation tell us about the data? - ANSWER ✅✅✅✅If it is skewed
and has a correlation more to the left (closer to -1), then the correlation is more
*negative*
If it is skewed and has a correlation more to the right (closer to 1), then the correlation is
more *positive*
Correlation _____ (does/doesn't) mean causation. - ANSWER ✅✅✅✅DOESN'T
Ex: drowning rates increase as ice cream sales do, that does not mean increased ice
cream sales caused the increased drowning rated.
What does a box and whisker plot show? - ANSWER ✅✅✅✅Whiskers = range of data
Box = upper and lower quartiles/extremes (25% and 75% marks)
Line in box = median
If there is a dot in center = mean
If mean and median overlie each other = similar values = normally distributed dataset
what is data? - ANSWER ✅✅✅✅recorded, disparate facts
what is information? - ANSWER ✅✅✅✅structured facts
knowledge? - ANSWER ✅✅✅✅the result of considering those structured facts in a
larger context
