Nul hypothesis: The direction of long shore drift is not from west to east.
We can disprove the hypothesis by finding the angle of the beach and the size and volumes of its stones at five transects between two groynes.

Types of data
Quantitative and qualitative data
Qualitative data is the used to collect the opinions of one person or a group of people. An example of qualitative data is if you ask people what their opinion is on the rock groynes on the beach this is qualitative data because it is the opinions/views of the people. Quantitative data is the information about figures and quantities. Therefore the width of the beach is quantitative data because it contains figures.
Primary and secondary data
Primary data collection is the data collected by yourself for your own research. Secondary data is the data collected by other people for their research.
Random data, stratified data and systematic data.
random sampling is a technique where we are selected a sample to study from a larger area. the sample that you are chosen to study is entirely by chance by using a random number generator. stratified data sampling is where the researcher divides up the population into sub groups( strata) and then the researcher takes samples from each subset. A stratified sample is obtained by taking samples from each stratum or sub-group of a population. systematic data is where you use a system to study a certain area for example measuring the angle of the beach every 3m
ways we collect the different types of data
random data is obtained by using a random number generator and then the using the number that comes up to assign groups of people to study that area. stratified data is obtained. stratified data would be collected by taking samples from each sub group of a population. systematic data is obtained by using a system or being consistent for example every 5 m.
transect
A transect is a followed route where measurements are taken or data is collected . An example of this is measuring the gradient of the beach every 3m along a transect.
how we collected the data
Measuring stones: during the trip we collected the length, width and area of stones from every 3m intervals on the transect. we collected 10 stones every 3 m using the quadrat and we used the calipers to measure the length and width of the stones and we multiplied the length and the width to find out the area.
measuring the angle of the beach: to find the angle of the beach we used a tape measure and systematic sampling to collect the data at regular 3 meter intervals. A meter ruler was used to mark each 3 meter interval and the gun clinometer was placed on top of the first ruler and it was aimed at the second to measure the gradient of the beach every 3m. the results are shown below.

measuring the volume of 10 stones: we collected 10 rocks from each section again using the quadrant and added them to 1000ml of water and we recorded how much the water rose, and recorded how much volume 10 stones had.
