What BIO2010 covers
The path runs from Research Questions, Hypotheses and Reproducible R Workflows through Distributions, Uncertainty and Statistical Questions to Building and Testing Biological Models.
Research Questions, Hypotheses and Reproducible R Workflows
research question · testable hypothesis · reproducible workflowEstablish the analytical object
The Week 1 material treats a question as an analytical design decision, not as a decorative opening sentence. Start by identifying the biological unit and outcome.
- research question
- testable hypothesis
- reproducible workflow
- turn a biological observation into a testable question, a directional or non-directional hypothesis, and a notebook record that another analyst can rerun
- A precise hypothesis does not rescue convenience sampling, non-independent units or a response measured after the analyst has seen the treatment labels.
Biological Data, Tidy Structure and Wrangling
observational unit · tidy data · data transformationStart from the observed condition
Week 2 moves from data types and distributions into wrangling because structure controls what later functions can legitimately compute. Before pivoting, filtering or joining, write down what one row means.
- observational unit
- tidy data
- data transformation
- diagnose variable roles and reshape a biological table without changing the observational unit or silently manufacturing replication
- Tidy structure improves computation; it does not establish independence, correct measurement error or justify excluding an inconvenient value.
Visualisation as Biological Evidence
visual encoding · distribution · overplottingFix scale, actor and purpose
The schedule places visualisation before error, design and formal models because a graph is the first model check. Start with the response scale and explanatory type.
- visual encoding
- distribution
- overplotting
- choose a graphical encoding that exposes distribution, replication and uncertainty instead of using decoration to imply a stronger result
- A compelling plot can reveal a pattern and a problem, but it cannot by itself distinguish treatment effect from confounding, selection bias or pseudoreplication.
Experimental Design, Independence, Error and Bias
independence · pseudoreplication · biasEstablish the analytical object
The short-answer materials repeatedly distinguish observation from experiment and replication from repeated measurement.
- independence
- pseudoreplication
- bias
- identify the true replicate, separate random error from systematic bias, and match a biological claim to the allocation and sampling process
- Statistical significance cannot repair a confounded treatment, a biased sensor or an allocation scheme with one treatment unit per condition.
Distributions, Uncertainty and Statistical Questions
standard deviation · standard error · confidence intervalStart from the observed condition
The Week 2 material pairs centre with spread because a biological average without a distribution can be misleading. Mean and standard deviation describe different features from median and interquartile range.
- standard deviation
- standard error
- confidence interval
- summarise biological variation with statistics that match the distribution and distinguish observed spread from uncertainty about an estimate
- A narrow interval can be precisely wrong when sampling is biased, measurements are systematically displaced or the model ignores clustering.
Linear Models I: Single-Factor ANOVA
factor · ANOVA · residualFix scale, actor and purpose
Week 7 introduces single-factor ANOVA as a linear model rather than a stand-alone ritual. The response for unit i in group j can be represented as a grand mean plus a group effect and residual.
- factor
- ANOVA
- residual
- express a one-factor comparison as a linear model, partition variation and connect the omnibus test to biologically planned contrasts
- ANOVA describes conditional group differences in the analysed design; it does not establish causation when habitat was observed rather than randomly assigned.
Linear Models II: Regression and Diagnostics
slope · intercept · leverageEstablish the analytical object
Week 8 extends the linear-model framework from group indicators to a continuous explanatory variable. The fitted line separates systematic mean structure from residual variation.
- slope
- intercept
- leverage
- estimate and interpret a continuous relationship while checking linearity, variance, influence and the range over which prediction is defensible
- Do not extrapolate the fitted line beyond the sampled environment or interpret an observational slope as a treatment effect without a causal design.
Multiple Explanatory Variables and Categorical Association
conditional coefficient · interaction · chi-square testStart from the observed condition
Week 9 adds multiple explanatory variables, forcing interpretation to become conditional. A coefficient is no longer a marginal association when correlated predictors share information.
- conditional coefficient
- interaction
- chi-square test
- separate conditional regression effects from interactions and use contingency evidence when both measured variables are categorical
- A multiple model can reduce some confounding but cannot prove that all relevant causes were measured or that adjustment variables were chosen without bias.
Building and Testing Biological Models
state variable · recurrence relation · validationFix scale, actor and purpose
Weeks 11 and 12 move from fitting relationships to constructing process models. The workshop population balance can be written as n′ = n(1+b)(1−d)+m, separating starting abundance, births, deaths and migration.
- state variable
- recurrence relation
- validation
- translate a biological process into states, flows and assumptions, iterate it transparently, and test whether its behaviour answers the intended question
- A simple recurrence is a conditional thought tool, not a forecast beyond its parameter range, time step, population closure and measurement assumptions.
The current offering is represented as one source-controlled product, including any declared alias rather than a duplicate shell.
The subject's opening move is concrete: Biological questions become testable only when the response, explanatory structure, population and observational unit are explicit. That principle makes research question more than vocabulary.
Students must state its object, scale and evidence before choosing an analytical procedure, technical control or communication tactic. The approach prevents a familiar term from being applied to the wrong unit or stakeholder.
The learning path begins with Research Questions, Hypotheses and Reproducible R Workflows, then develops through Biological Data, Tidy Structure and Wrangling, Visualisation as Biological Evidence.
The middle of the course uses Experimental Design, Independence, Error and Bias, Distributions, Uncertainty and Statistical Questions, Linear Models I: Single-Factor ANOVA. The final arc brings the reasoning together through Multiple Explanatory Variables and Categorical Association, Building and Testing Biological Models.
These are connected decisions rather than an unordered glossary.
Assessment in the current evidence is Pre-class preparation and participation 10%; Four topic quizzes 6%; Three assignments 34%; Theory and concept examination 50%. The recovered Semester 2 assessment structure totals 100%. Operational dates, venue and permitted resources remain controlled by the live Monash system.
Percentages describe the architecture, not the best revision order. A lower-weight task can still supply the practice needed for a later high-weight response, model or professional judgement.
The most demanding feature is this: The difficult move is preserving the real biological replicate from raw table through visualisation, model and interpretation.
A useful study record therefore has separate columns for observed fact, interpretation, mechanism, counter-evidence and decision. That structure makes the role of standard error visible and stops a conclusion from being defended by repeated descriptions of the same starting fact.
Worked practice should change one condition at a time.
Reconstruct the baseline case, predict what moves when an actor, input, comparison or constraint changes, and then test that prediction. When the result is unchanged, explain the invariant relationship. When it moves, identify whether the definition, mechanism, evidence quality or decision boundary changed first.
The course vocabulary is relational.
Terms such as research question, standard error and validation matter because they connect a question to an observable or controllable consequence. Learning them as isolated definitions is not enough. A student should be able to give an example, a non-example, the evidence needed for use and the condition that defeats the interpretation.
Source accuracy requires restraint.
Published course facts control identity, assessment and current-offering statements; examples in the resource are original practice. Silence is not converted into a reassuring rule. No additional course-specific hurdle is asserted from the recovered evidence.
Students should still verify deadlines, submission settings, venues, permitted materials and approved adjustments in the live institutional system.
Revision can be organised as a sequence of short loops. First retrieve the chapter map without notes. Next explain one mechanism in plain language. Then solve or analyse a changed case. Finally audit the answer for scale, evidence, stakeholder and boundary.
Each correction should name the first failed relationship rather than replace the entire response with a model answer.
For assessment writing, start from the instruction verb. Define only the concepts needed to answer it, trace the mechanism, use evidence to compare alternatives, and end with a conditional conclusion. For a calculation, preserve inputs, units, transformations and interpretation.
For a professional case, name responsibility, consequence and the signal that triggers review.
The free preview is most useful as a diagnostic. If research question can be defined but not applied, practise transfer. If standard error is asserted but not explained, draw the process or model. If validation never changes an answer, build a counter-case.
The objective is not more notes; it is a shorter, checkable path from evidence to judgement.
A final integrity check asks whether every numerical, technical or factual statement can be tied to the current course evidence and whether every original exercise is recognised as practice. It also asks whether the conclusion remains inside its population, observed range, system boundary or communication objective.
That discipline is central to Data Science for Biologists, not an editorial extra.
