qualitative data is data which has been collected to show detail and opinion for example "in this valley I can see that it shows," quantitative data is data which has been collected in large quantities showing for example measurements of a beach or mountain.
primary data is data which has been collected by you and you can verify from yourself, for example you can measure the surface area of a rock and you may present that as "primary data".
secondary data is data which has been collected from a third party source, for example Wikipedia or external geography books or sites.
random data is data collected from a random source of testers, this is useful for seeing external opinions and perspectives on a situation and to figure out an answer or conclusion.
stratified data is data which is collected on multiple levels, this can be used to collect comparative measurements between two different areas on a beach.
systematic data is regulated data that is taken at regular intervals. for example you could measure the height of a beach every 2 months or taking data of different age groups.
a transect is a way of measuring human and ecological changes.
Highcliffe Beach
Tuesday the 8th of November:
visit to Highcliffe beach to record data on longshore drift and other coastal data. we drew sketches and were able to create a rough outline of the beach. we measured the angular incline of the beach by using gun clinometers, you have two people holding meter sticks on top of the ground at regular intervals, for example 3 meters, and you then line the gun clinometer and line the sights with the top of the other persons meter stick, the press on the trigger of the gun until the angular disc has stopped moving, you then let go of the trigger and take a recording of the angle shown on the gun clinometer.
We also measured the average size of en pebbles in the chosen sectors using calipers to measure the width and the height, we also measured the volume by taking a jug of 100 ML of water and placing 10 pebbles into the jug, we then measure the change in the ML of the water.
null hypothesis
the direction of waves and longshore drift at Highcliffe beach does not move from west to east. We are able to disprove our theory by looking at the transect data we collected whilst on the beach. we can see that there is a shallow lower section of the beach that begins to amplify as you go up the beach. this is not apparent on the west side of the beach where the incline of the beach is relatively flat. this shows that sediment is moving along the beach on an easterly direction because it is piling up against the groyne on the east side meaning it is moving from west to east, disproving our hypothesis.
