Key Concepts

Qualitative Variables

Qualitative variables, also known as categorical variables, represent non-numeric categories or labels. They categorize data into distinct groups based on characteristics or qualities, such as color, type, or brand. These variables are typically described in words and are useful for grouping and classifying observations rather than performing arithmetic operations.

Quantitative Variables

Quantitative variables represent numerical values that can be measured and ordered. They involve amounts or quantities and are amenable to statistical analysis, allowing arithmetic operations such as addition, subtraction, and calculation of averages. These variables can be continuous, representing a full range of values, or discrete, representing countable quantities.

00:05 Have to differentiate between qualitative and quantitative data okay now i have to differentiate between qualitative and quantitative data let us go with qualitative data what is qualitative data qualitative data is non -statistical and is typically unstructured or semi -structured in nature okay this data isn't necessarily measured using hard numbers used to develop graphs and charts instead it is categorized based on properties attributes labels and other identifiers it is categorized it is categorized based on attributes based on attributes right it is based on categorized based on properties attributes labels and other identifiers qualitative data is generally you know it can be used to ask the question why it can be be used to ask the question why it is investigative and is often open -ended until further research is conducted generating this data from qualitative research is used for you know theorizations interpretations developing hypotheses and initial understandings okay for example what is the example of qualitative data if i say eye color if i say i color this is an example of qualitative data and i colors, c -o -l -i, i color.

01:50 This is an example of qualitative data or ranks.

01:55 Ranks.

01:56 What we are doing is we are arranging something categorically, right, based on how good something is.

02:03 So this is qualitative data.

02:04 What is quantitative? quantitative is statistical and is typically structured in nature.

02:10 This is statistical and typically structured in nature.

02:14 This is structured in nature.

02:24 Okay.

02:25 This type of data is measured using numbers and values.

02:29 Measureed using numbers and values.

02:33 Measured using numbers and values.

02:44 Quantitative data makes it more suitable candidate for data analysis...
