Quantitative Data Overview: • Deals with numbers. • Data can be observed but not measured. • Data which can be measured. • Length, height, area, volume, • Colors, textures, smells, weight, speed, time, temperature, tastes, appearance, beauty, humidity, sound levels, cost, etc. members, ages, etc. • Qualitative → Quality • Quantitative → Quantity
Qualitative Observations ●Hard to measure ●Describes the qualities of something ●Color - blue and white dress ●Taste - sour and bitter lemon ●Sound - blaring horn
