A student carried out an investigation into changes in plant succession on sand dunes in North Wales.

Figure 9 outlines the aim, the background theory, the hypothesis and the method used for the investigation.

Figure 9

Text summarising a student's plant species diversity investigation on sand dunes, focusing on marram grass coverage and distance from the sea.

Figure 10 is a sketch diagram of the dune system the student drew using theory from her textbook and aerial photographs of her chosen site. She added her sampling points.

Diagram showing plant distribution across sampling points from high tide to inland. Features include sand, marram grass, water-loving, and diverse plants.

Suggest why the student decided to collect data using a systematic sample.

Suggest how the student could present the data in Figure 11 to help show the relationship between distance from the high-tide mark and the percentage of marram grass.

The student tested for a correlation between the two sets of data in Figure 11, using a Spearman’s rank correlation test.

Figure 12 shows how she set out the data and started her calculations.

Table of sampling points with distance, rank of distance, marram grass percentage, rank, and calculations related to Spearman's rank correlation.

Figure 13 shows critical values of Rs for Spearman’s rank correlation coefficient.

Aim
The student’s aim was to investigate if there was a wider variety of plant species as you move inland and away from the sea.

Hypothesis
‘The percentage of species that is marram grass will decrease with distance from the sea.’

The student concluded that her data collection and processing had enabled her to reliably test her hypothesis and meet the aim of her enquiry.

Using Figures 9, 10, 11, 12 and 13, to what extent do you agree?
