What is stratified sampling
Creating a sample representative of s population
Proportions eg age group

What do you have to consider when presenting your data accurately
If it’s continuous or discrete data
If raw data or percentages are more useful
If data needs to be compared by location
What is continuous data
Doesn’t need to fit into certain values
Give 3 examples of continuous data
Time
Distance
Physical gradients
What is discrete data
Data that fits into particular categories
Eg number of students in a class
What is data analysis
Making sense of the data
Looking for patterns and anomalies
How can you ensure data is accurate
Take multiple readings and calculate a mean
Calibrate equipment
Identify the 6 stages in a geographical enquiry
Hypothesis
Fats collection.dsta presentation
Analysis of data
Concluding
Evaluating
How can you analyse quantitative data
Make averages
Find percentages
Look at range, median, mode
How can you analyse qualitative data
Look for common words/phrases
Turn it into quantitative by counting verbal responses
Highlight common themes
What is a conclusion
A summary of your findings in line with your initial inquiry question
What 3 things should a conclusion include
Key findings from data
Explanation of findings
Decision as to whether you can prove or disprove your hypothesis
What is an evaluation
A critique of what went well in the investigation and what you would do differently
What does validity mean
If the enquiry tested what it was meant to
What does reliability mean
Consistent results, same results if it was repeated
What aspects might affect the quality, reliability and validity of results
Sample size
Equipment
Time carried out
Location
Type of data (prim/secondary)
Sampling method
How can you reduce anomalies in data
Take multiple readings, then work out mean
