Data Analysis Flashcards
What’s quantitative data
Invloved numerical data, and no descriptions. The researcher will gather the data and put it into categories and rank them in order.
Graphs can be drawn
Collected from closed questions
Whats qualitative data
This involves non-numerical data, that allows for data with detail.
Open questions
Content analysis
Strengths of quantitative data
Can produce graphs
Easy to analysis of data (quick)
Results from, other studies can be compared to each other
Limitations of quantitative data
Can oversimplify complex behaviour
Possibly can be subjective
Strength of qualitative data
Represents complexity of human behaviour
Data is rich and detail
Gain access to thoughts and feelings
Limitaion of qualitative data
Difficult to draw conclusions and compare analysis
Time consuming to compare
Whats primary data
Data that is collected by yourself for a particular purpose such as an interview
What is secondary data
This is data collected by someone else that is used for your aim, such as articles
Strength of primary data
Data will be up to date
Data will be specific to the aim and fir for purpose
Limitaion of primary data
Time consuming to collect
Expensive to collect
Strength of secondary
Quick to collect
Cheap
Limiation of secondary
Possibly outdated
May not be specific to the aim of the study
Quality of the research is unknown to the researcher (could have mistakes)
Whats the mean
Add up all the numbers and divide them by the amount of numbers there are
How do you calculate the median
Put the numbers in numerical order and find the middle number (if there are 2 numbers in the middle, add them and divide by 2)
How do you calculate the mode
It’s the number that appears the most
Strength and limitaion of mean
Uses all the data involved therefore not missing out any anomalies, making at a very powerful measure of central tendency.
However, if there is an exceptionally high or low score it can cause the mean to be misleading.
Strength and Limitaion of the mode
The data will be unaffected by exceptionally high and low scores and its the simplest measure of control tendency to work out.
However, its the least sensitive as it tells us nothing about the other scores
Strength and Limitaion of the median
The data will be unaffected by high and low scores.
However its not representative of all the data and doesn’t work well with small sets of data
What is standard deviation
This is the average amount of all scores that deviate from the mean.
The larger the standard deviation, the greater the spread the scores are around the mean. This could suggests some anomalous results.
The smaller the standard deviation, the data is tightly clustered around the mean. This suggests that participants responded in a similar way
