WACE ATAR Mathematics Applications is the Year 12 applied-mathematics ATAR course in Western Australia, set by SCSA on Units 3 and 4. The exam has two sections: Section One Calculator-free (35%, 50 minutes, 5-10 questions) and Section Two Calculator-assumed (65%, 100 minutes, 8-13 questions), using short-answer and extended-answer questions rather than multiple choice. The six examinable topics are bivariate data analysis, growth and decay in sequences, graphs and networks, time series analysis, loans/investments/annuities, and networks and decision mathematics. There is no fixed pass mark; the standardised exam mark is combined 50/50 with school assessment and scaled into an ATAR. This 100-question bank provides original multiple-choice practice drilling the same Unit 3 and Unit 4 content and skills.

1In a scatterplot of two numerical variables, the variable plotted on the horizontal axis that is used to predict the other is called the:
A.Response variable
B.Explanatory variable
C.Residual variable
D.Dependent variable
Explanation: By convention the explanatory (independent) variable is placed on the horizontal axis and is used to explain or predict the response variable on the vertical axis. Identifying it correctly is the first step in bivariate analysis.
2A scatterplot shows points that fall close to a straight line that slopes downwards from left to right. The correlation is best described as:
A.Strong positive
B.Strong negative
C.Weak positive
D.No correlation
Explanation: Points lying close to a downward-sloping line indicate a strong, negative linear association: as one variable increases, the other decreases, and the tight clustering means the relationship is strong.
3Pearson's correlation coefficient r for a data set is -0.92. This indicates a:
A.Strong positive linear association
B.Strong negative linear association
C.Weak negative linear association
D.Perfect negative linear association
Explanation: An r value of -0.92 is close to -1, so the linear association is strong, and the negative sign shows the variables move in opposite directions. Values near +/-1 indicate a strong relationship.
4The least-squares regression line for predicting weekly sales (y, in $1000s) from advertising spend (x, in $1000s) is y = 3.2 + 1.5x. What does the gradient 1.5 mean in context?
A.Sales are $1500 when advertising is zero
B.Each extra $1000 of advertising is associated with $1500 more sales
C.Each extra $1000 of advertising is associated with $1500 less sales
D.Total sales equal 1.5 times advertising
Explanation: The gradient is the predicted change in y for each one-unit increase in x. Here, each extra $1000 (one unit of x) in advertising is associated with an increase of 1.5 units of y, i.e. $1500 in sales.
5Using the regression line y = 3.2 + 1.5x (sales in $1000s, advertising in $1000s), the predicted sales when advertising spend is $6000 is:
A.$9000
B.$12 200
C.$10 700
D.$11 000
Explanation: Advertising of $6000 means x = 6. Then y = 3.2 + 1.5 x 6 = 3.2 + 9 = 12.2, which is 12.2 thousand dollars, or $12 200.
6The coefficient of determination for a linear model is r-squared = 0.81. The best interpretation is that:
A.81% of the variation in the response is explained by the explanatory variable
B.The correlation coefficient is 0.81
C.81% of data points lie on the line
D.The gradient of the line is 0.81
Explanation: The coefficient of determination r-squared gives the proportion of the variation in the response variable that is explained by the linear relationship with the explanatory variable. Here that is 81%.
7If the coefficient of determination is r-squared = 0.64 and the scatterplot slopes upwards, the correlation coefficient r equals:
A.0.64
B.0.80
C.-0.80
D.0.41
Explanation: Since r = the square root of r-squared with the sign of the slope, r = sqrt(0.64) = 0.8, and because the slope is upward (positive), r = +0.80.
8A regression line is fitted to data on plant height (cm) versus age (days) for ages 5 to 30 days. Using the line to predict the height at age 60 days is an example of:
A.Interpolation
B.Extrapolation
C.Smoothing
D.Standardising
Explanation: Predicting outside the range of the observed data (here beyond 30 days) is extrapolation, which is unreliable because the linear pattern may not continue. Interpolation predicts within the data range.
9A residual is defined as:
A.Predicted value minus actual value
B.Actual value minus predicted value
C.Actual value divided by predicted value
D.The mean of the response variable
Explanation: A residual equals the observed (actual) value minus the value predicted by the regression line. A positive residual means the model under-predicted; a negative residual means it over-predicted.
10For the line y = 12 - 0.8x, the actual data value at x = 5 is y = 9. The residual at this point is:
A.+1
B.-1
C.+9
D.-8
Explanation: Predicted y = 12 - 0.8 x 5 = 12 - 4 = 8. Residual = actual minus predicted = 9 - 8 = +1, so the model slightly under-predicted the value.

About the WACE Maths Applications Exam

WACE ATAR Mathematics Applications is the applied Year 12 ATAR mathematics course in Western Australia, examined by the School Curriculum and Standards Authority (SCSA) on Units 3 and 4. The course focuses on using mathematics to solve practical problems involving statistics, finance, sequences and networks. Unit 3 covers bivariate data analysis, growth and decay in sequences, and graphs and networks; Unit 4 covers time series analysis, loans/investments/annuities, and networks and decision mathematics. The written examination has a calculator-free Section One (35%, 50 minutes) and a calculator-assumed Section Two (65%, 100 minutes) using short-answer and extended-answer questions. The examination mark is combined equally with school assessment to produce the final course mark used in ATAR calculation.

Exam sponsor: School Curriculum and Standards Authority (SCSA), Western Australia. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Two sections. Section One Calculator-free is worth 35% of the exam (5-10 questions); Section Two Calculator-assumed is worth 65% (8-13 questions). Both use short-answer and extended-answer questions covering Unit 3 and Unit 4 content.

Time Limit

150 minutes working time (Section One 50 minutes, Section Two 100 minutes) plus 10 minutes reading time before Section Two.

Passing Score

No fixed pass mark. The standardised examination mark is combined 50/50 with the school-assessment mark to form the final course mark, which TISC scales into an ATAR; there is no simple pass or fail cut-off.

Exam / Certification Fees

There is no separate sitting fee for the ATAR course examination; Year 12 exam costs are covered by WACE enrolment and school fees administered through SCSA.

WACE Maths Applications: Suggested Study Strategy

1Drill the calculator-free skills separately: read scatterplots, interpret a regression equation, find a sequence's nth term and read network diagrams without relying on technology.
2For bivariate data, always state the direction, form and strength of a relationship and never confuse a strong correlation with a causal link; watch for confounding variables.
3Learn your CAS finance solver cold for loans, investments and annuities, and check answers by stepping the recurrence relation through one or two periods by hand.
4For time series, practise the full chain: smooth with moving averages, find seasonal indices by the average percentage method, deseasonalise, fit the trend line, then re-seasonalise the forecast.
5In networks, memorise the conditions for Eulerian and Hamiltonian graphs and practise Prim's, Kruskal's, Dijkstra-style shortest paths and critical-path forward/backward scanning until they are automatic.
6Work through several past SCSA examinations under timed conditions and mark them against the official marking keys to learn how method marks are awarded.
