STA1010 Statistical Methods for Science
CALCULATORS IN EXAMS in Semester 1, 2010
Students are encouraged to bring into lectures and laboratory support class a calculator that can handle two variable input (reasonably cheap scientific calculators have this feature). They should be used along with MS Excel in support classes. Graphics calculators may be used in support classes but will NOT be allowed in the examination. You should practise using the appropriate calculator before the exam. ONLY A NON-PROGRAMMABLE, NON-GRAPHIC, STANDARD SCIENTIFIC CALCULATOR WILL BE PERMITTED IN EXAMINATIONS IN THIS UNIT.
1. Calculators may be used in the exam ONLY where specifically approved by the School of Mathematical Sciences Chief Examiner. 2. The following calculators (with the authorised Monash UniversityScience sticker ) are approved for use in the STA1010 examinations: a) Simple calculators with arithmetic functions only b) Scientific calculators, that are not programmable, but are capable of 1-variable and 2-variable statistics. (recommended)
Examples of APPROVED Scientific Calculators:
Caieion: FM-83 Canon: F720, F720i Casio: fx-82, fx-83, fx-85, fx-100, fx-115, fx-350, fx-570, fx-911, fx-991 and fx-992 series Citizen: SR-135, SR-260, SR-270, SR-275 Hewlett Packard: HP-6s, HP-8s, HP-9s, HP-10s, HP-30s Texas instruments: TI-30 and TI-34 series Texet: Albert 2, Albert 3, Albert 5 Sharp: EL-506, EL-509, EL-520 and EL-531WH series 3. IMPORTANT: Only these listed calculators or their equivalent, and with the authorised Monash University-Science STICKER will be allowed into the examination by the invigilators. The sticker will be available from Dr Dianne Atkinson in her office (28/449). 4. Calculators MUST NOT BE PROGRAMMABLE OR GRAPHIC. Such will NOT be permitted into the examination. Examples of NON-approved calculators are given below. 5. A calculating device that incorporates a set of keys whose primary function is to represent the alphabetic characters (eg a QWERTY keyboard) is not deemed to be a calculator for the purpose of this examination, and will not be allowed. Electronic diaries and mobile phones are NOT ACCEPTABLE. The sticker is the same as used by some Chemistry and Physics units, but you must verify the validity of the calculator in the unit concerned. 6. No candidate may claim special consideration because of the lack of a calculator or any breakdown or fault in the calculator.
CALCULATORS NOT APPROVED for use in STA1010 Examinations are:
Programmable scientific calculators such as: Casio: fx-50F Plus, fx3650P and fx5800P series, Citizen: SRP-175 Hewlett Packard: HP-20s, HP-33s, HP-35s Sharp: EL-5250 And Graphic calculators such as: Casio: cfx-9850, fx-9860 and Algebra fx2.0and ClassPad 300 series Citizen: SRP-325G, SRP-400G Hewlett Packard: HP-9g, HP-39gs, HP-40gs, HP-48gll, HP-50g Texas instruments: TI-73, TI-83, TI-84 and TI-89 series, Nspire, Voyage200 Texet: GR4F-X3 Sharp: EL-9900 You are reminded that possession of unauthorised materials in an exam is discipline offence under Statute 4.1 of Monash University Regulations.
