地理卷一 Q1 詳盡評改報告

For advantages, ~~a~~ convenience sampling is fast and simple to carry out. Since students may need to choose the sampling point according to their wish and convenience without prior procedures to determine what types of buildings to be sampled. For disadvantages, convenience sampling is subjective because its non-probability, not every members have the same chance to be selected. Students may chose the sampling ~~step~~ out of their convenience and wish.

~~Firstly,~~ students would first check the buildings directory of the seven buildings by ~~an~~ observation. They would count the number of ~~#~~ flats of different types of industrial activities and jot down the number into the record sheet by tallies. The students would also categorize the flats ^using into different ~~two~~ types of activities. For instance, food production and processing, garment and ~~text~~ ^textile and plastic products would be categorized into 'manufacturing activities'. After that, the students will count the number of companies involved in ~~each~~ ^manufacturing activities in each building and count ~~out~~ the total number of flats inside the building. After acquiring both numbers, students would calculate the proportion of manufacturing activities in each building by dividing 'manufacturing activities''s number by the total number of flats inside the building.

The conclusion is that the lower the accessibility, ~~[illegible struck line]~~ the higher proportion of manufacturing activities in the selected buildings. In the scatter diagram, I will first record the proportion of manufacturing activities in the selected building by dotting at the graph with their respective proportion. Next, I will observe the location of the dot. ~~[two struck-out lines, illegible]~~ , Next, I will draw a best-fit line at a place with similar distance to all the dots. If there are extreme datas, ~~a~~ I would also ~~neglect~~ ^remove it before drawing the line, thus ~~so~~ having a conclusion of a positive relation.

Firstly, I would collect the primary data with the record sheet on more buildings in the industrial area. As with convenience sampling, only the buildings of one road is being selected for sample. It would be better to select a few more buildings at the another part of the industrial area, for instance, at the northeastern and eastern part of the area. This could provide me with a more comprehensive knowledge and understanding on the relation between accessibility and the intensivity of manufacturing activities as the accessibility of the eastern part of the area is relatively low too. Secondly, I would conduct a questionnaire with the people working at the industrial area. This is because people like building security and manufacturing companies' labours could have a better understanding about the proportion of manufacturing ~~comps~~ activities in the buildings. By firstly setting questions, such as asking interviewees to use a scale from 1 to 10 to describe the intensivity of manufacturing activities, to considering who to interview, what sampling methods to choose ~~interviewees~~ ^interviewees, such as quota sampling and convenience sampling, to choosing the mode of ~~the~~ questionnaire, such as face-to-face or video call. Conducting a questionnaire allows me to have a more authentic understanding on the intensivity of the manufacturing activities regarding to the extent of accessibility. Thirdly, I would ~~use~~ have a field trip on testing the pollution level of the zone. As manufacturing activities often emits more pollutants. ~~St~~ Students could use instruments like PM2.5 meter and carbon monoxide meter to record the pollutant level at different ~~sites~~ [unclear: sites]. By calibrating the instrument and holding it up high, the number could be recorded after it stabilised. Results like a higher reading ~~co~~ should be found at places with more manufacturing activities, thus coming to the conclusion of a relationship between ~~accessibility~~ ^walking distance and intensivity of manufacturing activities. Fourthly, I would use a timer ^and a counter to count the flow of large vehicles, ~~of~~ such as trucks. As trucks are often seen at places with manufacturing activities due to logistic needs, by setting a time and counting the flow and number of trucks ^with a counter, ~~students~~ could find out that the more manufacturing activities, the higher flow and number of trucks. Thus coming to a positive relationship between walking distance from the bus terminus and the intensivity of the manufacturing activities. Fifthly, I would use a dB meter, which is also called noise meter, to test the sound level in the industrial area. As manufacturing activities often produce more sound, we can use a noise ~~to~~ meter to test the noise level at different ~~sites~~ [unclear: sites], and come up with a conclusion that the lower the accessibility, which is the more walking distance from the bus terminus, the higher the noise level, which indicates on higher intensivity of manufacturing activities. Lastly, by recording all the datas from the five data ~~sets~~ above, I would make a rating based on the environmental level and the intensivity of manufacturing activities, with respect to their accessibility. ~~[struck line]~~ The higher the number (mark) represents a higher pollution level and a higher intensivity of manufacturing activities. By comparing the numbers of different building ~~sites~~ [unclear: sites], a conclusion of the lower accessibility, the higher the intensivity of manufacturing activities could be found out, with enriched primary datas.
