Diversity in days (participants was on different days)
Diversity in experiment day’s time slot
Diversity in participant’s demographic profile
Uniformity in season (April 2016)
Data samples has record of time and place
Human perception: Physiological response are time dependent (temporal)
City dynamics: Location depending (non-temporal
