4.1.2 Concept 1: The Quantitative Revolution

Guiding Question: Why did geography become a quantitative discipline, and how did it change how we study space?

  • Describe the origins of the Quantitative Revolution in geography and how political and academic pressures pushed geography towards a “spatial science” 
  • Identify assumptions built into quantitative reasoning (measurability, objectivity, universality)
  • Reflect on critiques and limits of the Quantitative Revolution from human and critical geographers
  • Interpret early spatial models
  • Explain how MAUP, spatial dependence, spatial heterogeneity, and distance decay influence the structure and interpretation of spatial data
  • Connect the “spatial problem” to violations of independence in classical inference

4.1.3 Concept 2: Data and Descriptive Statistics

Guiding Question: How do we summarize and describe variation in data?

  • Classify different types of geographic data and variables (e.g., primary vs. secondary, individual vs. aggregated, qualitative vs. quantitative, level of measurement), and explain how these distinctions influence analysis
  • Explain the major sources and  key dimensions of geographic (coverage, resolution, scale, temporality, completeness, positional accuracy, and bias) and how these dimensions influence analysis.
  • Describe basic geographic data structures (vector/raster)
  • Explain and evaluate measurement quality in geographic data, including precision, accuracy, validity, and reliability.
  • Summarize and interpret attribute data using descriptive statistics (central tendency, dispersion, shape) and data visualizations

4.1.4 Concept 3: Spatial Description

Guiding Question: How do we summarize and describe variation in geographic data?

  • Use maps to visually analyze spatial patterns and understand the role of classification schemes for grouping spatial data values
  • Compute and interpret spatial descriptive statistics (mean center, standard distance, standard deviational ellipse) and explain how they extend non-spatial descriptive measures

4.2.2 Concept 4: Probability

Guiding Question: How can we use probability to quantify uncertainty and understand patterns in events?

  • Compute and interpret simple event (empirical) probabilities
  • Compute and interpret probabilities for discrete and continuous data using theoretical probability distributions
  • Visualize probability across space

4.2.3 Concept 5: Inferential Statistics

Guiding Question: How can we use sample data to understand and estimate characteristics of a population?

  • Explain the Central Limit Theorem and why it allows us to generalize from samples to populations.
  • Identify how sampling design affects representativeness and uncertainty (simple, systematic, stratified, cluster, spatial hybrid).
  • Estimate and interpret population parameters (means and proportions) from samples (calculate point estimates and confidence intervals)

4.2.4 Concept 6: Hypothesis Testing

Guiding Question: How can we generate and test hypotheses about a population using sample data?

  • Distinguish between the null (H₀) and alternative (H₁) hypotheses
  • Identify the two types of error in hypothesis testing (Type I and Type II)
  • Formulate testable hypotheses and identify an appropriate statistical test based on the characteristics of the data 
  • Run and interpret one sample and two sample t-tests to compare means between one or two groups
  • Run and interpret Chi-Square tests to assess relationships between categorical variables
  • Differentiate statistical significance from substantive importance

4.3.1 Assessment Structure:

  • Competency: Completes Lab 7-10 with Meets Expectations
  • Mastery: Completes Case Study #3 with Meets Expectations

4.3.2 Concept 7: Patterns in Events

Guiding Question: How can we assess the distribution/pattern of individual events in space?

  • Distinguish random, clustered, and regular event patterns
  • Compute and interpret quadrat tests to assess spatial randomness (CSR) and determine statistical significance
  • Compute and interpret nearest neighbor statistics to assess spatial randomness and determine statistical significance
  • Visualize event patterns using point maps and density surfaces (kernel density estimation)
  • Evaluate the effects of scale and edge boundaries on event pattern analysis

4.3.3 Concept 8: Patterns in Values

Guiding Question: How can we detect patterns in attribute values across points or areas?

  • Define spatial influence (neighborhoods) for point and aerial data using KNN, Queens Case, and distance-based measures
  • Compute and interpret measures of global autocorrelation (Moran’s I)
  • Compute and interpret measures of local autocorrelation (LISA) and use mapping to identify and analyze spatial patterns (hot-spots, cold-spots)
  • Discuss how scale, zoning, and MAUP influence patterns

4.3.4 Concept 9: Bivariate Spatial Relationships

Guiding Question: How can we examine and model relationships between two variables across space?

  • Visualize and interpret bivariate relationships using maps and scatterplots
  • Explain how linear regression extends hypothesis testing to relationships between two variables
  • Estimate and interpret simple bivariate regression models in a geographic context
  • Diagnose spatial dependence in regression residuals using spatial autocorrelation measures
  • Estimate and interpret spatial regression models 
  • Compare non-spatial regression results with spatial regression results to pick an appropriate model

4.3.5 Concept 10: Spatially Continuous Surfaces

Guiding Question: How can we estimate values at unsampled locations and understand spatial clustering and uncertainty across continuous surfaces?

  • Compute point estimates at unsampled locations using Thiessen polygons, IDW, and k-point means.
  • Define and interpret the semivariogram to understand spatial clustering, correlation, and range of influence.
  • Approximate uncertainty for predictions using sample variance or semivariogram-based approaches and interpret the implications.
