Geagte Student
Hierdie studiebrief bevat terugvoering oor Werkopdrag 01 en 02, en modelantwoorde. Let
asseblief goed op na die puntetoekenning. Die korrekte antwoorde op die meerkeusevrae word
gegee en bespreek. Vergelyk jou werkopdragantwoorde met die memoranda om te sien waar jy
gefouteer het. Onthou, die terugvoering oor Werkopdrag 03 verskyn in die studiegids.
Die studiebrief verskaf ook verdere inligting oor die eksamen. ’n Afskrif van die
Oktober/November 2013-vraestel is aangeheg (sien die bylae). Werk deur die vraestel sodat jy

1. FEEDBACK ON ASSIGNMENT 01 / TERUGVOERING OOR WERKOPDRAG 01
This is the first compulsory assignment that you had to submit and it contributes 10% towards
your final mark. See page 10 in Tutorial letter IOP2601/101/3/2014 for details on how to
calculate your final mark.
A full memorandum is provided here. Compare your answers with the following memorandum
and make sure that you understand this first part of Descriptive Statistics before you continue
with the next assignment on the rest of Descriptive Statistics and Inferential Statistics.
Hierdie werkopdrag is die eerste verpligte werkopdrag wat jy moes indien en dit tel 10% van jou
finale punt. Die berekening van die finale punt word op bladsy 11 in Studiebrief
IOP2601/101/3/2014 verduidelik.
’n Volledige memorandum word hier verskaf. Vergelyk jou antwoorde met die memorandum en
maak seker dat jy hierdie eerste deel van Beskrywende Statistiek verstaan voor jy begin met die
volgende werkopdrag oor die res van Beskrywende Statistiek en Inferensiële Statistiek.
QUESTION /VRAAG 1-30 [30]
The correct answers are given in the second column next to each question number.
Die korrekte antwoorde verskyn in die tweede kolom langs elke vraagnommer.

Antwoord
1 2 Inferential Statistics is applicable here, because a sample is being used
to make inferences about the population.
Inferensiële Statistiek is hier van toepassing, want ’n steekproef word
gebruik om gevolgtrekkings oor ’n populasie te maak.
2 3 The research process is discussed on page 5 of the study guide. Note
the sequence of the steps followed.
Die navorsingsproses word op bladsy 5 van die studiegids bespreek. Let
op die volgorde van die stappe wat gevolg word.
3 3 The 85 members represent the total members who are of interest to the
research; they are the population. See Tredoux and Durrheim (2002,
2013) for a definition, and some activities on pages 21 and 22 of the
study guide.
Die 85 lede verteenwoordig die totale aantal lede waarop die navorsing
van toepassing is; hulle is dus die populasie. Sien Tredoux en Durrheim
(2002, 2013) vir die definisie, en die aktiwiteite op bladsy 21 en 22 in die
studiegids.
4 2 The subset of the population and the members selected for evaluation
are 30 members, representing the sample. See Tredoux and Durrheim
(2002, 2013) for a definition, and some activities on pages 21 and 22 of
the study guide.

Antwoord
Die substel van die populasie en die 30 lede wat gekies is vir evaluering
verteenwoordig die steekproef. Sien Tredoux en Durrheim (2002, 2013)
vir die definisie, en die aktiwiteite op bladsy 21 en 22 in die studiegids.
5 4 The difference between independent and dependent variables is
discussed on page 13 of Tredoux and Durrheim (2002, 2013); activities
relating to these variables appear on pages 17 and 20 of the study
guide. Performance is the dependent variable, because whether
members of the organisation work in the office or work from home
presumably affects performance.
Die verskil tussen die onafhanklike en afhanklike veranderlikes word op
bladsy 13 in Tredoux en Durrheim (2002, 2013) bespreek; aktiwiteite oor
veranderlikes verskyn op bladsy 17 en 21 in die studiegids. Prestasie is
die afhanklike veranderlike omdat dit waarskynlik beïnvloed word deur
die feit dat lede van die organisasie óf by die kantoor óf by die huis werk.
6 3 The type of work environment (office or home) has none of the
properties of measurement; therefore the nominal scale is the correct
scale. Measurement scales are discussed on pages 11 and 12 of
Tredoux and Durrheim (2002, 2013); activities relating to measurement
scales appear on pages 19 to 21 of the study guide.
Die tipe werksomgewing (kantoor of huis) het geen eienskappe van
meting nie, dus is die nominale skaal die korrekte skaal. Metingskale
word bespreek op bladsy 11 en 12 van Tredoux en Durrheim (2002,
2013); aktiwiteite oor metingskale verskyn op bladsy 19 tot 21 in die
studiegids.
7 1 The Real Lower Limit (RLL) can be found halfway between 3 (from the
class interval that would be before 4–6) and 4 (from the class interval of
interest of 4–6). The RLL for the class interval 4–6 is 3,5. See page 24 of
Tredoux and Durrheim (2002, 2013), and page 38 of the study guide for
discussions about the RLL. The activities are on page 40 of the study
guide.
Die Werklike Ondergrens (WOG) word halfpad aangetref tussen 3 (van
die naburige klasinterval wat voor 4–6 val) en 4 (van die klasinterval van
belang van 4–6). Die WOG vir die klasinterval 4–6 is 3,5. Sien bladsy 24
van Tredoux en Durrheim (2002, 2013), en bladsy 38 in die studiegids
vir besprekings hiervan. Die aktiwiteite verskyn op bladsy 40 in die
studiegids.
8 4 The real upper limits are discussed in the same section as the RLL
above (question 7). The Real Upper Limit (RUL) for class interval 10–12
is 12,5.
