Data Analysis Flashcards
Uses Analytical and Logical Reasoning to gain information from the data
DATA ANALYSIS
Process of organizing and interpreting collected data to answer the research problem
DATA ANALYSIS
to find meaning in data so that the derived knowledge can be used to make informed decisions
DATA ANALYSIS
used in descriptive studies
DESCRIPTIVE STATISTICS
used in descriptive studies as a means of describing the nature and characteristics of the event under investigation
DESCRIPTIVE STATISTICS
Initial step in the analysis of data in analytic research
DESCRIPTIVE STATISTICS
Science involves in the collection, organization, analysis and interpretation of numerical data
STATISTICS
a table of rank ordered scores that shows the number of times each value occurred
FREQUENCY DISTRIBUTION
constructed by grouping the scores into classes, or intervals, where each class represents a unique range of scores within the distribution
GROUPED FREQUENCY DISTRIBUTION
classes are mutually exclusive (no overlap) and exhaustive within the range of scores obtained
GROUPED FREQUENCY DISTRIBUTION
MEASURES OF CENTRAL TENDENCY
- MEAN
- MEDIAN
- MODE
layman’s concept of average
MEAN
it is sensitive to extreme values
MEAN
is used especially when other statistical techniques like testing of hypothesis are to be applied to the data
MEAN
the middlemost observation in a set of data arranged in numerical order
MEDIAN
it is not sensitive to extreme values
MEDIAN
it is used when distribution is markedly skewed
MEDIAN
the most frequently occurring value among the observations
MODE
unaffected by extreme values
MODE
not used in higher statistical analysis
MODE
used for continuous and symmetric data
MEAN
such as when your data is normally distributed
MEAN
used for ordinal data or for a numerical data whose distribution is skewed
MEDIAN
dealing with ordinal data
MEDIAN
used primarily for bimodal distributions
MODE
the least used of the measures of central tendency
MODE
can only be used when dealing with nominal data
MODE
Describe the degree of scatter of the different values of the variable
MEASURES OF DISPERSION OR VARIATION
highest – lowest value
RANGE
Maximum- minimum
RANGE
the average of squared differences from the mean
VARIANCE
It is simply the squared value of the standard deviation
VARIANCE
looks at how spread out a group of numbers is from the mean
STANDARD DEVIATION
square root of the variance
STANDARD DEVIATION
Measures variability in relation to the mean
COEFFICIENT OF VARIATIONS
It is useful in comparing two series for sets of data, especially when such sets or series are expressed in different units of measurements
COEFFICIENT OF VARIATIONS
Summary indices describing the “central point” or the most characteristic value of a set of measurement
MEASURES OF POSITION/LOCATION
values of random variable X that divides the observations into 100 equal parts
Percentile
values of random variable X that divides the observations into 10 equal parts
Decile
values of random variable X that divides the observation into 4 equal parts
Quartile
Can be observed and recorded
QUALITATIVE DATA
Non-numerical in nature
QUALITATIVE DATA
Also known as Categorical Data
QUALITATIVE DATA
A process on which it is needed to focus on some of the data and disregarding other parts of it shall be emphasized and seen
DATA WINNOW
Time-consuming process of manually coding qualitative data
HAND CODING
More faster and more efficient than hand coding
QUALITATIVE SOFTWARE PROGRAMS
Uses Colaizzi’s strategy of descriptive phenomenological data analysis
PHENOMENOLOGICAL RESEARCH
Has systematic steps such as:
➢ Open coding
➢ Axial coding
➢ Selective coding
GROUNDED THEORY
Use of detailed description of the setting or the individual
CASE STUDY AND ETHNOGRAPHIC RESEARCH
STEPS IN QUALITATIVE DATA ANALYSIS
- Organize and Prepare for the data analysis
- Read all the data
- Start Coding all the data
- Generate Description & Themes
- Represent the Findings
- Interpret the Findings
a table that contains a list of predetermined codes that researchers use for coding the data
CODEBOOK
rendering of information on people, places, or events in a setting.
Description
major findings in qualitative studies. Often used as headings in the findings section of studies
Themes
is the process of organizing the transcript data by bracketing chunks of text and writing a word representing the text
Coding
