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
