Term
 Define Temporal Analysis
Definition
 The study of time.
Term
 What are the two reasons we analyze time?
Definition
 1. To understand what has already happened 2. To predict what will happen in the future
Term
 What are the two elements that are typically combined to identify a discrete temporal location?
Definition
 Date and Time.
Term
 What does A.M. stand for?
Definition
 Ante Meridian
Term
 What does P.M. stand for?
Definition
 Post Meridian.
Term
 When electronically stored,Date and Time data are often merged into a single "date/time" field. What are the 3 formats used for storing this data?
Definition
 1. Text field 2. Numeric field 3. A Specialized date/time field type
Term
 Define Temporal Distribution
Definition
 How events are situated throughout the study area in relation to one another.
Term
 What are the 3 classes of distribution?
Definition
 1. Clustered events tend to occur in close proximity to one another. 2. Uniform events tend to occur far apart from one another. 3. Random events are neither clustered nor uniform. (All can apply to geography or time)
Term
 The Nearest Neighbor Test, Ripley's K, and Moran's I are all tests to measure what?
Definition
 Distribution
Term
 What is tempo?
Definition
 Tempo is a measurement of tendency
Term
 What are the 3 types of tempo?
Definition
 1. Acceleration occurs when the interval between events decreases as the number of events decreases 2. Decceleration occurs when the interval between events increases as the number of events increases 3. Stabilization occurs when the interval between events neither increases nor decreases as the number of events increases
Term
 The Least Squares Best Fit method can be applied to a tempogram to calculate what?
Definition
 A trend line.
Term
 Tempo suffers limitations, one of which being that it does not account for terminal velocity.   What is terminal velocity?
Definition
 The fastest rate at which events can occur.
Term
 In order to make sense of an otherwise chaotic tempo or distribution, we look for ________________.
Definition
 Correlations   We look for correlations between the interval and other another variable, such as value of goods obtained.
Term
 True or False? There's no such thing as "random" when it comes to human bahavior.
Definition
 True.
Term
 Define the type of temporal falacy known as a spurious relationship.
Definition
 A spurious relationship is when two factors have no causal connection, but appear to have one due to a third unknown variable.
Term
 What are the 3 questions an analyst should ask when confronted by an apparent temporal correlation?
Definition
 1. Is the correlation logical? 2. Is the correlation causal? 3. What have you forgotten?
