# What is the difference between a qualitative observation and a quantitative obeservation?

quantitative observation is observing numbers such as "there are twenty potatoes". Qualitative observation is observing anything that is not countable such as "the potatoes are all brown"

### What is the main difference between qualitative and quantitative?

A qualitative observation has to do with things you can't count, "The fish has black scales" is a qualitative observation. A quantitative observation has to do with things you can count, "The fish has 125 scales" is a quantitative observation. You can combine these two, an example would be "The fish has 125 black scales."

### What is the main difference between qualitative and quantitative observation?

A quantitative [think 'quantity'] observation is an observation that you can relate specific numbers to. For example, a quantitative observation might be "It rained 1.5 inches yesterday." A qualitative [think 'quality'] observation is an observation that does not include specific numbers, such as "It rained a lot yesterday" or "It rained more yesterday than today."

### What is the difference between a qualitative observation and quantitative observation?

A qualitative observation is an observation of what something is, such as, I saw a pig, I saw sunlight, I saw a plane flying by, I saw a green fluid, etc. A quantitative observation is a numerical measurement of something, such as, I have 7.9 grams of sugar, the current air temperature is 13o C, the car is traveling at 52 kph, etc.

### What is the difference of qualitative observation from quantitative observation?

Qualitative observation is becoming aware of an object/event by using properties related to numbers and/or measurements. Weight, height, etc. Anything measured with a numeric value is considered qualitative. Quantitative observation is identifying objects according to characteristics that cannot be easily measured or counted. Cloudiness, texture, smell, etc. are all different things that fit into the category.

### Difference between qualitative and quantitative?

Qualitative and quantitative data are both 2 important types of data. Qualitative data is data based on observation and description. An easy way to remember this, Qualitative ---> QUALity. Examples of qualitative data are when you record colors, smells, textures, etc... Quantitative data is based on numerical values. An easy way to remember this, Quantitative ---> QUANTity. An example of quantitative data are any type of numerical values.

### What is the main difference between qualitaive and quantitative observations?

Think of it this way... Qualitative- Quality (root word) Quantitative- Quantity (root word) Thus, qualitative observation is different from a quantitative one. Here's an example: Qualitative Observation- I observed a classroom of 30 children for a 3-month period (1 hour/day). I observed their speech pattern as they engaged in oral activities in groups. (This is an ex. of an observation that is done specifically and for a good time period) Quantitative Observation- I observed 5…

### What is the difference between qualitative and quantitative observations?

Listen to the words qualitative and quantitative and see the part where it is bold. Qualitative is the way of analysis to a substance through its quality, like reaction to a re-agent etc. (normally chemistry). Quantitative observation however is purely on quantity mass, mass/volume ratio etc. (normally physics). Basically, qualitative observations are descriptions that don't involve numbers or measurements, but, on the other hand, quantitative observations do.

### What is the difference between quantitative observation and descriptive?

There are two main methods of research. These are quantitative and qualitative methodologies. Quantitative methods are based on numbers. that is statistics, measurements, values and calculations. Qualitative observes behaviors, visual characteristics and behaviors of what is/are being investigated. For example the Doppler Shift has qualitative characteristics of color (blue versus red shift). Quantitative aspects of the Doppler Shift of space objects would be their velocity, age, and compositions by percent.

### How would you determine the difference between a qualitative and a quantitative measurement?

You would determine the difference by qualitative is for your observation and quantitative is determining the amount of something. Qualitative measurements give you a comparison with other things or a general characteristic (for example, "it turns yellow", which indicates PRESENCE of some reagent; or "it smells like rotten eggs", possibly indicating ethyl mercaptan). A quantitative measurement tells you a number in some dimension, such as the wavelength of light of that "yellow" solution, the numerical…

### What is the difference of quantitative chemistry and qualitative chemistry?

The difference is found in the definitions for quantitative and qualitative. Quantitative deals with quantity, therefore amounts, numbers such as: --how much of a certain substance you have --how tall something is --how heavy a chemical is (molar mass) These are things that can be recorded objectively. Qualitative on the other hand deals with how something appears, such as: --coloration -- texture These are a lot less precise measurements because they are subjective.

### What is the difference between quantitative and qualitative measurements?

If I had a 25% solution of sodium chloride and I did a quantitative measurement, the interest would be in HOW MUCH was present. In this case it would be 25%. If I did a qualitative measurement, all we would be interested in is - WHAT IS PRESENT. In this case sodium chloride and water. In simple terms, qualitative is "What is present" and quantitative is "How much is present"
