Question

identifying qualitative and quantitative data
the data collected about a colony of bacteria into qualitative or quantitative data.
circular in shape
spreads across plate
200 purple colonies total
stained purple
75 colonies did not stain purple
55 colonies grew at room temp
qualitative data
quantitative data

Explanation:

Step1: Define Qualitative/Quantitative Data

Qualitative data is non - numerical (descriptive), quantitative is numerical (involves numbers).

Step2: Classify "circular in shape"

"Circular in shape" is descriptive, so it's qualitative. Add to Qualitative Data.

Step3: Classify "spreads across plate"

"Spreads across plate" is descriptive, so it's qualitative. Add to Qualitative Data.

Step4: Classify "200 purple colonies total"

"200" is a number, so it's quantitative. Add to Quantitative Data.

Step5: Classify "stained purple"

"Stained purple" is descriptive, so it's qualitative. Add to Qualitative Data.

Step6: Classify "75 colonies did not stain purple"

"75" is a number, so it's quantitative. Add to Quantitative Data.

Step7: Classify "55 colonies grew at room temp"

"55" is a number, so it's quantitative. Add to Quantitative Data.

Qualitative Data:

• circular in shape
• spreads across plate
• stained purple

Quantitative Data:

• 200 purple colonies total
• 75 colonies did not stain purple
• 55 colonies grew at room temp
