CSV file: Quality Stats

There is an option to download the Quality Stats in the form of a CSV file. This file contains the following fields:

• string study_id - UUID,
• string item_id - UUID,
• string item_filename - the name of your file, as it was named while adding to the study,
• string item_cdn_url - URL to the tested item saved on our servers,
• string participant_id - UUID,
• string participant_external_id - UUID (in case you provide one by connecting the study with an external tool, i.e., a survey),
• string participant_display_name - a name that a participant gives while asked about a name, gender, and age at the end of the study (if you have chosen that option), i.e., "Anna, Female, 27",
• string participant_tags - tags assigned to a participant (added by the study owner),
• int participant_quality_grade - participant's grade from 1 to 6 where:
• 1 = very low,
• 2 = low,
• 3 = average,
• 4 = good,
• 5 = very good,
• 6 = perfect;
• int participant_quality_grade_item - item's grade from 1 to 6 where:
• 1 = very low,
• 2 = low,
• 3 = average,
• 4 = good,
• 5 = very good,
• 6 = perfect;
• int test_item_display_order - a number indicating the order in which the items were displayed,
• int exposure_number - (only applicable for Website Mockup studies) indicates the time the participant saw an item, i.e., 1 means that the participant saw this item for the first time,
• int data_integrity - informs about how many gaps in the data collected there are,
• int gaze_on_screen - informs about how much of the eye-tracking test time participant looked at the screen.
• int sampling_rate - informs about how many samples per second are collected (30 Hz means that each second, on average, 30 samples are collected),
• int gaze_vs_click_accuracy - (if applicable) informs about the difference (distance) between the gaze and click (in the moment of clicking) - this parameter may not be reliable, as people may click on a particular area, without looking at it,
• int gaze_count - number of gazes on the item counted for the participant,
• int fixation_count - number of fixations on the item counted for the participant,
• notes - this column contains:
• RealEye version,
• fixation filter settings:
• gazepoint interpolation (Hz) - to improve calculations we interpolate the data to 60 Hz;
• gazepoint interpolation max gap (ms) - we interpolate data if the timestamp gap between two input values is not bigger than this value (50 ms);
• gaze velocity threshold;
• min. fixation duration (Ms);
• max. fixation duration (Ms);
• moving median range (Ms);
• saccade max duration (Ms);
