Data Analysis and Interpretation
-
Establish Clear Objectives: Define the specific hypotheses or questions to be addressed by the experiment.
-
Review Experimental Setup and Protocols: Ensure that the data collection methods and procedures were sound and appropriate.
-
Visualize and Summarize Data: Create graphs, tables, and histograms to present the raw data in a meaningful way. Identify trends, outliers, and uncertainties.

Apply Statistical Tests: Use statistical methods (e.g., t-tests, ANOVA) to assess the significance of differences between experimental groups or conditions. Determine uncertainties and confidence intervals.
-
Identify Patterns and Relationships: Examine the data for correlations, trends, and patterns. Identify potential causal relationships and exclude confounding factors.
-
Consider Error Sources: Evaluate the sources of experimental error and their potential impact on the results. Estimate uncertainties and account for error propagation.
