Froggy Jumps River Data Scatter QuizVersión en línea Test your data plotting insight por Mark Cowan 1 What is a key advantage of using a scatterplot for data? a Displays precise values for every data point b Prevents outliers from appearing c Shows trend or correlation between two variables 2 What does a scatterplot help you identify easily? a The median of each variable b Anomalies in the data c Exact mean value 3 Which issue can occur because of overlapping points? a It improves readability b It may obscure data patterns c It increases legend size 4 If discharge increases downstream, what is implied about the relationship? a Positive correlation b Negative correlation c No correlation 5 What does a Spearman’s value of +0.65 suggest at 99.5% confidence? a A statistically reliable positive association b A perfect correlation c A weak, unreliable link 6 What is a reported average discharge at site 1 in cumecs? a 4.3 cumecs b 57.1 cumecs c 13.28 cumecs 7 How much did the discharge increase downstream according to the report? a 2 times b 13.28 times c 4.3 times 8 Why might a graph show anomalies between sites 31-38? a The data is perfect with no issues b Human error, environmental factors, or unforeseen events c Only random sampling error 9 Which factor can decrease velocity through the river bed? a Friction from sediment b Water temperature c Air pressure 10 What can improve measurement precision in velocity studies? a Using more accurate equipment b Ignoring calibration c Reducing sample size 11 What is a common disadvantage of scatterplots? a Requires no axes b May be confusing without a data table c Always shows exact values 12 What does the scatterplot indicate about distance downstream? a Discharge is independent of distance b There is a relationship with discharge c Discharge decreases with distance 13 What causes discharge to increase downstream in this study? a Two tributaries joining between sites b River width narrows c Temperature rises 14 What does the term ‘anomaly’ mean in data analysis? a A typical data point b A result that doesn’t fit the pattern c A confirmed outlier always 15 What should researchers consider about sampling for confidence? a Time of day is irrelevant b Color of markers c Sampling size and duration 16 Which result supports the hypothesis in this study? a Discharge constant across sites b Discharge lower downstream with no trend c Discharge higher downstream with correlation 17 What is the aim of the River Leven fieldwork? a To investigate how the River Leven changes along its long profile. b To compare the River Leven with other rivers. c To measure the river width at multiple points. 18 What was the hypothesis for the River Leven study? a The discharge will increase as you move downstream. b The river's width will stay constant downstream. c The discharge will decrease as you move downstream. 19 At site 1, what was the average discharge reported in the River Leven study? a 0.0 cumecs b 4.3 cumecs c 57.1 cumecs
