Not answered Marked out of Select one: 2.00 a. Focus & Context tasks will show some of the data in more detail than others. b. Focus & Context tasks do not support exploration of the data on the edges of the data view. c. The filter task retains an overview. https://moodle.gla.ac.uk/mod/quiz/review.php?attempt=4257512&cmid=4514515 Page 2 of 7 Start exam quiz HERE: Attempt review | Moodle 02/08/2024, 12:49 PM Question 10 The visualisation pipeline: Complete Marked out of Select one: 2.00 a. highlights the importance of user interaction b. depicts four independent processes from data to view c. includes a step for transforming raw data to visual structure Question 11 Colour: Complete Marked out of Select one: 2.00 a. can be defined as cool (e.g. green) or warm (e.g. red) b. only has eight named hues, plus white c. saturation is bad for representing ordered data Question 12 The Gestalt laws: Complete Marked out of Select one: 2.00 a. have no rank order between them b. only relate to static images c. relate to top-down visual processing Question 13 Perception Complete Marked out of Select one: 2.00 a. of targets amongst distractors with respect to speed sometimes depends on the number of distractors b. of shape is quicker than colour c. mostly uses bottom-up processing of the physical components of the visual scene Question 14 The task of analysing data: Not answered Marked out of Select one: 2.00 a. may include the activity of deriving new data b. does not include the task of presenting data c. means outliers are investigated when focussing on distribution targets

Marked out of Select one: 2.00 a. can be recognised pre-attentively b. are either ordered or quantitative c. include some variables that are strongly related to each other Information Click here to

interesting in a visualisation: Complete Marked out of Select one: 2.00 a. correlations can be investigated when focussing on attribute targets b. a viewer is usually interested in particular data points c. paths relate to attributes whose values are linked to each other Question 17 Representations Complete Marked out of Select one: 2.00 a. if external, can amplify cognition b. of information can be in the mind or on paper c. of cognitive effort were calculated in the Larkin & Simon (1987) paper Question 18 When analysing data: Complete Marked out of Select one: 2.00 a. you would usually create a summary of the data for each task b. qualitative data is summarised by numerical calculations c. the analysis of quantitative data requires the use of themes Question 19 Data Not answered Marked out of Select one: 2.00 a. collected by observation requires a systematic process b. collected for an evaluation is typically quantitative c. collected by observation is always subjective

Not answered Marked out of Select one: 2.00 a. preference data is related to perception data because they are both subjective b. preference data is related to perception data because they are both objective c. an audio recording of a participant's actions is qualitative and subjective data Question 21 Attributes Complete Marked out of Select one: 2.00 a. are associated with data items b. if categorical, can be naturally ordered c. are categorical or sequential Question 22 Data types: Complete Marked out of Select one: 2.00 a. can group data into a table data structure b. describe data that is always available c. include tables, networks and fields Question 23 Successful methods of drawing graphs Complete Marked out of Select one: 2.00 a. typically depend on the type of graph to be

queries c. makes queries accessible and usable to everyone Question 26 Colour Not answered Marked out of Select one: 2.00 a. is defined by hue, lightness, saturation and (maybe) brightness b. value is bad for representing ordered data c. should never be used to encode any dimension of a multidimensional data set Question 27 Data Complete Marked out of Select one: 2.00 a. collected for an evaluation is typically formative b. collected for an evaluation is typically performance data c. collected by observation cannot include product data Question 28 Formative evaluation Complete Marked out of
