Criterion A: The body of the work is further subdivided so that phases of the exploration are clearly indicated.

Comment: Although the student subdivided the work further, they didn't include a clear indication of the subdivision as the headings for the subsections included the same formatting as those for the sections. This was considered incorrect

Criterion A: The topic of the Internal assessment is stated clearly and explained in the introduction

Comment: The student indicated the topic of the internal assessment in the subsection of "Aim" of the exploration which indicated three aims of the work

Criterion A: The introduction includes a general description of the student's approach to the topic and what area of the math curriculum the exploration focuses on

Comment: The student explained the topic of their family relocation and the choices they have to make concerning it as well as indicated the use of statistics in the exploration which was all indicated in the introduction

Criterion A: The conclusion is a summary of the outcomes and a response to the aim of the exploration stated in the introduction

Comment: Although there is a good summary of the findings of the investigation, the student did not provide a final statement of the most beneficial place for their father to work. The student should have indicated such a place and indicated the best place for the job as well as compare the findings of the investigation

Criterion A: The exploration is clear and understandable throughout - no rereading of sections is necessary

Comment: The student provided no symbols of what they were calculating. The student should have indicated the symbols for the concepts and ensured that the clear order of calculations was provided

Criterion A: The use of technology, when applied, is clearly indicated and explained

Comment: The student indicates the use of technological software and sites such as Google Maps and Desmos, hence the use of technology is clearly explained

Criterion A: If analytical software is used, its purpose is described and the link to it is provided

Comment: The student provided all the necessary links to Google Maps and Desmos which ensured that the purpose and link were included

Criterion A: If analytical software is used, its purpose is described and the link to it is provided

Comment: The student provided all the necessary links to Google Maps and Desmos which ensured that the purpose and link were included

Criterion A: If analytical software is used, its purpose is described and the link to it is provided

Comment: The student provided all the necessary links to Google Maps and Desmos which ensured that the purpose and link were included

Criterion A: The use of technology, when applied, is clearly indicated and explained

Comment: The student indicates the use of technological software and sites such as Google Maps and Desmos, hence the use of technology is clearly explained

Criterion A: The graphs, tables, and diagrams are present in appropriate places (in the body paragraphs, after their descriptive introduction)

Comment: Although the student provided a graph of the area in which they rejected the hypothesis in the T-test, however, no description was made. The student should have first described the means of rejection of the hypothesis and then introduced the figure

Criterion A: The graphs, tables, and diagrams are present in appropriate places (in the body paragraphs, after their descriptive introduction)

Comment: The tables are unnecessarily provided for calculations. The student should have included the calculations in a thread instead of them being included in the table. If the student insisted on including it in the table, they should have provided a description beforehand

Criterion A: All information outside of the syllabus scope is referenced <i style='font-size: 11px'>(using footnotes or in-text citations)</i>

Comment: Although the information outside the syllabus is included and the reference in the work was provided, the student did not provide correct references. The student should have formatted the references similarly to the ones provided above in the bibliography

Criterion A: All mathematical formulae, equations, and other calculations are centered

Comment: The student did not center the values or equations in the work, hence the criterion was not fulfilled

Criterion A: All mathematical formulae, equations, and other calculations are centered

Comment: The student did not center the values or equations in the work, hence the criterion was not fulfilled

Criterion B: Correct mathematical notation, symbols, and terminology are used consistently and correctly

Comment: The student used the incorrect multiplication sign. The sign that should have been used was "×", hence the criterion cannot be fulfilled. The mistake is not detrimental, however, it should have been fixed

Criterion B: Key terms/variables are defined and explained when first introduced

Comment: The student explained the key variables such as the rental rate or fixed interest rate in the work, hence the criterion was fulfilled

Criterion B: The main concepts are described in the introduction

Comment: If the methodology section were to be considered as a part of the introduction, the main concepts are described there as the descriptions of the T-test and Voronoi diagrams are explained in the section

Criterion B: Additional terms are defined in detail in appropriate places (dependent on the development of the exploration)

Comment: The student explained the additional terms in the work such as the variables in the amortization formula or the perpendicular bisector equation, hence the criterion was fulfilled

Criterion B: Additional terms are defined in detail in appropriate places (dependent on the development of the exploration)

Comment: The student explained the additional terms in the work such as the variables in the amortization formula or the perpendicular bisector equation, hence the criterion was fulfilled

Criterion B: Additional terms are defined in detail in appropriate places (dependent on the development of the exploration)

Comment: The student explained the additional terms in the work such as the variables in the amortization formula or the perpendicular bisector equation, hence the criterion was fulfilled

Criterion B: Multiple forms of mathematical representation: formulae, diagrams, tables, charts, graphs, and models are present but used only if appropriate

Comment: The tables provided for the calculations were not necessary, hence the criterion was not fulfilled. The student should have included a calculation thread instead

Criterion B: All mathematical calculations are explained and any data presentation is described

Comment: All the calculations, graphs, and tables are described and explained in the work as the student included introductory descriptions and descriptions after the insertion, hence the criterion was fulfilled

Criterion B: All mathematical calculations are explained and any data presentation is described

Comment: All the calculations, graphs, and tables are described and explained in the work as the student included introductory descriptions and descriptions after the insertion, hence the criterion was fulfilled

Criterion B: All mathematical calculations are explained and any data presentation is described

Comment: All the calculations, graphs, and tables are described and explained in the work as the student included introductory descriptions and descriptions after the insertion, hence the criterion was fulfilled

Criterion B: The graphs, tables, and diagrams are labeled (titled and numbered) at the bottom

Comment: The student provided no labeling for the figures, tables, or graphs present in the investigation. The student should have provided a label at the bottom of the additional content included with the title and numbering, e.g. Figure 2. Critical value table for the t value
