Basics
A number computed from a larger collection of numbers which collectively constitute a sample of data
Statistic
A standard of performance or best practice for a particular process or outcome
benchmark
Best way to display trends over time
Line graph
Name
Nominal data
term used for massive amounts of information that can be interpreted by analytics to provide an overview of trends or patterns
big data
Decision making, healthcare operations needs, public health needs
Reasons for Studying Statistics
the science of examining raw data with the purpose of drawing conclusions about that information
data analytics
Best way to display data that are parts of the whole
Pie chart
expresses the comparative evaluation of various characteristics or entities
Ordinal data
-collection of data that reflects all aspects of hospital operations and that is used for reporting and analysis.
-rather than backing up data, it lets users find subject-oriented information on demand.
clinical data warehouse
Provide information about the health of people and their utilization of healthcare services
Health Statistics
-summarization of data
-describes raw data
-helps us see what was done in the past
-most statistics we use falls into this category
descriptive analytics
This type of data display tool is used to display discrete categories
Bar graph
whole numbers
discreet data
process of extracting and analyzing large volumes of data from a database for the purpose of identifying hidden and sometimes subtle relationships or patterns and using those relationships to predict behaviors
data mining
Describe what the data shows about the characteristics of a sample; tells information about a particular population
Descriptive statistics
-is a branch of data mining concerned with the prediction of future probabilities and trends
-also called forecasting
-is about understanding the future and keeping in mind nothing can predict the future with 100% certainty
-takes information from the EHR and data warehouses and tries to make the best guess based on patterns
predictive analytics
An effective tool for planning and tracking the implementation of a project
Gantt Chart
decimal numbers
-trend in healthcare to move towards this
-involves systematically reviewing clinical data and making treatment decisions based on the best available information
-this would be tedious and most impossible for a physician to complete manually
evidence-based medicine
Helps us make inferences about a larger group of data by drawing conclusions from a smaller group of data
Inferential statistics
-related to descriptive and predictive analytics but it tries to automatically process new data to improve the accuracy of predictions and provide better decisions
-allows users to prescribe a different amount of possible actions
-predicts what will happen but also provides recommendations that will take advantage of the predictions
-allows them to look at possible outcomes and come to a decision
-relatively new
prescriptive analytics
Diagram used to graphically show the relationship between 2 numerical values.
Scatter diagram
Unprocessed facts and figures
data
organization-wide framework for managing information throughout its lifecycle and support the organizations strategy operations and regulatory legal and environmental requirements
-includes policies, procedures, and protocols
