Engineering Data Analysis (TOPIC 1)
Exam-Graded A
Is a branch of science which deals with the collection, presentation, analysis, and
interpretation of a set of numerical data. - ANSWER-Statistics
The foundation of Statistics, which can be transformed into useful facts and information
that an analyst or decision maker can use. - ANSWER-Data
The fundamental characteristic of data is _________. - ANSWER-Variability
Two (2) Types of Statistics - ANSWER-Descriptive Statistics and Inferential Statistics
Statistics aimed to? - ANSWER-To uncover structure in data, and to explain variation in
the data.
Methods concerned with the analysis of a subset of data leading to predictions or
inferences about the entire set of data. - ANSWER-Inferential Statistics
Methods concerned with collecting, describing, and analyzing a set of data without
drawing conclusions (or inferences) about a large group. - ANSWER-Descriptive
Statistics
Types of Data - ANSWER-Quantitative Data and Qualitative Data
Describes qualities or characteristics. It is collected using questionnaires, interviews, or
observation, and frequently appears in narrative form. - ANSWER-Qualitative Data
Are used when a researcher is trying to quantify a problem, or address the "what" or
"how many" aspects of research question. It is data that can either be counted or
compared on a numeric scale. - ANSWER-Quantitative Data
Types of Qualitative Data - ANSWER-Nominal and Ordinal
Types of Quantitative Data - ANSWER-Interval and Ratio
Can be arranged in any particular order and no indication of distance between positions.
However, no arithmetic can be done on this data.
e.g. Level of satisfaction - ANSWER-Ordinal Data
, Consists names, labels, or categories, gender, major in college. Numbers or symbols
are used to classify.
e.g. Sex - ANSWER-Nominal Data
Are similar to interval data, with the extra property that division maybe carried out.
There exists a natural zero.
e.g. Score in an exam - ANSWER-Ratio Data
Are similar to ordinal data, with the extra property that subtraction maybe carried out.
There is no natural zero.
e.g. Temperature - ANSWER-Interval Data
Methods of Collecting Primary Data - ANSWER-Observation, Interview, Questionnaire,
Schedule, Case Study, Survey, Panel, and Experimentation
This method is quite popular, particularly in case of big enquiries. - ANSWER-
Questionnaire Method
It is one of the most important method for the study of social problems. - ANSWER-
Schedule Method
Asking people, firms, etc., questions either by personal interviews or by mailed
questionnaires. - ANSWER-Survey Method
Data is collected from the same sample respondents at the same time either by email or
by personal interview. - ANSWER-Panel Method
This method of collecting data involves presentation or oral-verbal stimuli and reply in
terms of oral-verbal responses. The interviewer asks questions, which are aimed at
getting information required for the study, to respondents. - ANSWER-Interview Method
A method under which data from the field is collected with the help of observation by the
observer or by personally going to the field. - ANSWER-Observation Method
It is essentially an intensive investigation of the particular unit under consideration. -
ANSWER-Case Study Method
There is direct human intervention on the conditions that may affect the values of the
variable of interest. - ANSWER-Experimentation
Types of Interview Method - ANSWER-Telephonic Interview and Personal Interview
Types of Observation Interview - ANSWER-Structured and Unstructured Observation,
Participant and Non-participant Observation, Controlled and Uncontrolled Observation
