aim of a line graph
show changes over time at a series of data points connected by straight lines
1 of 67
strengths of a line graph
easy to read and interpret // shows specific values // can predict future results //
2 of 67
disadvantages of a line graph
can only be used to show data over time // have to use consistent scale on axis
3 of 67
aim of a bar graph
visually represent data that is categorized
4 of 67
strengths of a bar graph
east to read and interpret // easy to construct // can compare categories
5 of 67
disadvantages of a bar graph
can only be used for discrete data //
6 of 67
aim of a chloropleth map
the show how something varies between different areas using colours or patterns
7 of 67
advantages of a choropleth map
easy to read as it is visually effective // general anomolies can be identified
8 of 67
disadvantages ofchoropleth maps
gives false impressions with abrubt changes at boundaries // variations within an area are hidden // exact figures arent shown
9 of 67
aims of a dot map
to show distribution of something across an area
10 of 67
advantages of a dot map
can represent a large range of items // easy to interpret and analyse
11 of 67
disadvantages of dot maps
can be uncler if dots are overcrowded // does not represent small countries i.e. same number of dots in a small country to large looks very different
12 of 67
aim of flow lines
movement of a variable from one area to another
13 of 67
advantages of fow lines
width of line is proportional to value // visual
14 of 67
disadvantages of flow lines
hard to draw // doesnt say why // overcrowded
15 of 67
aim of proportional bars and squares
to show the proportion of the variable by the size of the bar
16 of 67
advantages of proportional bars and squares
easy to read and interpret //
17 of 67
disadvantages of proportional bars and squares
doesnt say why // overcrowded in small areas
18 of 67
aim of proportional circles
to show the proportion of a vaiable by the size of the circle
19 of 67
strengths of proportional circles
easy to interpret and read // represent a large range of data
20 of 67
disadvantages of proportional circles
difficult to produce / not accurate // overlaps can occur so confusing
21 of 67
aim of sketch maps
a drawing/ sketch of an area to show key features using annotations and keys
22 of 67
advantages of sketch mps
shows main features of an area // used when finding sample areas // good annotations give specifics
23 of 67
disadvantages of sketch maps
may not be an accurate representation // needs to be correctly annotated in detail to be usefull // only shows 1 view and 1 point in time
24 of 67
aims of an ordinance survey map
a map which shows all parts of an area such as roads building and trees using symbols
25 of 67
advantages of ordinance survey maps
allows you to find specific features on a large map using grid references // also shows altitude
26 of 67
disadvantages of ordinance survey maps
areas may be changed and so are not accurate in the map // errors made when reading the map may be tiny but in real life its a lot bigger
27 of 67
aims of weather maps
a map displaying various meteorological features across an area using symbols
28 of 67
advantages of weather mpas
helps plan geographical fieldwork / help predict natural disasters
29 of 67
disadvantages of weather maps
weather is unpredictable and can change easily // it is a statistical analysis so it is never deterministic
30 of 67
aims of an isoline maps
lines drawn on a map to show areas that share a common value and a gradual change in an area
31 of 67
advantage of an isoline map
shows gradual change not abrupt // can see areas of equal value // can see clear boundaries in an area
32 of 67
advantages of man whitney
states whether the difference is significant or due to chance // use data sets of different sizes // good at dealing with skewed data
33 of 67
disadvantages of man whitney
lengthy calculations mean prone to human error // does not explain why there is a difference
34 of 67
advantages of chi-squared
states whether there is an association or it occured by chance // good to use on data that is put in catagories
35 of 67
disadvantages of chi-squared
does not say why they are associated // liable to researcher bias as catagories are chosen by them
36 of 67
advantages of spearmans rank
can show positive and negative correlation // used with raw data
37 of 67
disadvantages of spearmans rank
needs at least ten sites to be accurate
38 of 67
explain how and why you selected the topic for your fieldwork investigation
easily accessible (A169) / lot of change in a small distance / national park little human interference
39 of 67
justify one method used to collect data in your investigation
flow vane= 4 sites equally distributed so we could see rate of change (BM) / did the centre left and right to get an average / did the same at every site
40 of 67
in light of your investigation suggest how your investingation could be developed
compare to another river / compare to a different course of the river / do in a different season to see effects of weather / closer sites to get more accurate results
41 of 67
assess the usefullness of one method of data presentation you used
cross sectional diagram= easy to read / compares both depth and width / easy to compare between sites / results could be skewedby rocks / confsing due to different scales on each axis
42 of 67
choses one method of data analysis that you used and why you used it
spearmans rank= tells us if the relationship is significant of velocity / our result was 7.3 which is significant at the 99% level / says if its positive or negative
43 of 67
assess the implications of your conclusions for geographers
outliers show that rivers dont always change like a texbook / other school groups can use it as secondary data / north yorkshire park might use it / other geographers form new hypothesis based on it
44 of 67
risks and how to manage them during the investigation
speared by a ranging pole- carry face down / drowning in the river- upper course in small groups / slip or fall - suitable footwear and check the weather / hypothermia and cold- check weather and suita\ble clothing
45 of 67
aim of a scatter graph
displays plotted values of 2 variable with a line of best fit to show average
46 of 67
advantages of scatter graph
shows a correlation between 2 variable // can be continuous
47 of 67
disadvantages fo scatter graphs
takes time and accuracy to construct / sometimes diificualt to draw a line of best fit
48 of 67
aim of a pir chart
used to compare catagories within a data set
49 of 67
advantages of a pie chart
easily understood universally / summerise large amounts of data visually
50 of 67
disadvantages of pie charts
not easy to know exact values / cant show change over time / confusing if there are a lot of variable
51 of 67
aim of a triangular graph
graph with 3 axis that compares the % of 3 variables
52 of 67
advantages of a triangular graph
compares 3 variable / relative importance can be seen
53 of 67
disadvantages of triangular graphs
confusing if there are many plotted points / only be used fro 3 variables that only measure %
54 of 67
aim of a kite diagram
change in the % of a variable over a certain distance e.g. vegetation
55 of 67
advantages of kite diagrams
species can be compared / compares 2 variables / easy and clear
56 of 67
disadvantages of kite diagrams
only compares 2 variables / difficult to identify anomolies
57 of 67
aim of a radial diagram
values extend out from a central point to show how it changes
58 of 67
advantages of radial diagrams
compare multiple sets of data / lots of data on one graph / visual representation
59 of 67
disadvantages of radial diagrams
cant link to a statistical test / difficult to spot anomolies / doesnt say why
60 of 67
aim of a logarithmic scale
a scale of measurement that uses the logarithmic of physical quantity
61 of 67
how did you analyse results
rank distance downstream + velocity / ranked both sets 1-10 smallest = 10 largest = 1 / worked out the difference in ranks / squared this number and added them up / put that number into spearmans rank formula got the result 0.73
62 of 67
what was the outlier for water width and at what site did it occur
0.76 at site 5
63 of 67
what was the outlier for velocity and at what site did it occur
0.245 at site 8
64 of 67
what was the outlier for discharge and at what site did it occur
0.0708 at site 8
65 of 67
what did velocity increase from and what did it end as
0.167 to 0.304
66 of 67
how was the data you collected accurate and reliabel
did the same at each site / used flow vane / startified sampling / each group did it at each site so took the average
