Pie Chart
How should the steps in the analysis process progress
From specific items to general items or from the smallest part or element to the complete subject
What is a branch of mathematics concerned with the collection of numerical facts
or
A set of concepts, rules, and procedures used to analyze numerical information and organize and illustrate it in the form of tables, graphs, and charts
or
Data that can be represented numerically

Survey
What are the three methods of research?
Survey, observation, and experimentation
What is a method of research that is used to monitor the subjects actions without directly interacting with them
Observation
How many approaches to the problem should be developed as a minimum
2
What is used to determine the likelihood of an event occurring
Risk analysis
What is an analysis based on the relationship between effort/cost and results/benefit
Cost benefit analysis
What is an analysis that involves looking at each step in the process and determining the best way to do it
Process analysis
What is an analysis that occurs when current policies are analyzed for effectiveness and enforcement
Policy analysis
What is it analysis used to determine the most efficient ways to provide a program or service by looking at each program component
Program analysis
What is an analysis or assessment that is conducted to determine the types of services that an organization is currently delivering and compare them to the services the community desires
Needs analysis
What is the term used to describe a process, product, or activity that produces the desired result or meets its intended purpose
Effective
What term best describes the minimum cost for the maximum effect
Efficient
What visual aid emphasizes the relationship between two variables
Dot Charts
What visual aid uses pictures or maps to display data
Pictogram
What type of visual aid is similar to a histogram and is a diagram or map that highlights the occurrence of certain types of events
Hot chart
What is the most commonly used method for gathering information or statistical data
Survey
How long does it generally take to analyze a program
Six months
What is the biggest disadvantage of a survey
Limited by the amount of in-depth questioning that can be accomplished
What is the process of methodically examining the various parts of an item, project, or incident
Analysis
What implies an objective study of the widest array of facts
Analysis
What is the term that refers to the accuracy or truthfulness of a measurement
Validity
What is a term synonymous with repeatability which reveals consistent results over time
Reliability
What is a term for a statistic describing the location of the distribution
Average
What does the term describing an expression of the relative size of two numbers by showing one divided by the other
Ratio
What is a method used to analyze or represent statistical data
Statistical procedure
What term refers to the arrangement of values of the variable showing their observed or theoretical frequency of occurrence
Statistical distribution
What is the term sometimes used to determine the central tendency, which is a typical or representative value for a set of data
Statistical analysis
What is this some of the values divided by the number of values
Mean
What is the value which divides the values into two equal halves, with half of the values being a lower and half being higher
Median
What is the term to describe the most frequently occurring value or values in the data set
Mode
What is considered the most compelling reason to use statistics according to the fire data analysis handbook
Analysis gives insight into fire and life safety problems
What is the process establishing the worth or value of each of the parts based on the desired outcome
Evaluation
What is the process of methodically examining the various parts of an item, project, or incident
Analyzing
What is it called when a person or organization takes action that will prevent future expenses
Cost avoidance
What are costs that will occur if specific actions are taken
Financial consequences
Generally how long does a policy analysis take
One year
Who should perform a policy analysis
If it is a big problem an externalorganization should handle the process. If it is a small problem then an internal committee can be formed
How long do you program analysis take
Six months
Risk analysis relies on determining what
Probability
What is establishing how effective and efficient a person, a program, a process, or an item is compared to a benchmark or established set of criteria
Evaluating
What is the preferred approach to personnel evaluations
In formal approach
What are the only records that are not available to the public
Medical and personnel records
What is the main benefit to a telephone interview
Very efficient use of time and funds
The best form of survey is what
Face-to-face interview
