What following statements?
a. there is no mode
b. there are two modes
c.there are three modes
To determine which statements about a numerical data set could be correct, we need to understand the characteristics of a data set.
1. Statement 1: "The data set consists of a set of numerical values."
This statement is correct. A data set typically consists of a collection of numerical values or observations.
2. Statement 2: "The data set consists of a set of textual values."
This statement is incorrect. A data set generally contains numerical values rather than text values. However, in some cases, textual data can be converted or summarized into numerical values to create a numerical data set.
3. Statement 3: "The data set consists of a mixture of numerical and categorical values."
This statement is possible. While data sets are primarily composed of numerical values, it's also possible to have a mixture of numerical and categorical values. Categorical variables represent qualities or characteristics that are not measured on a numeric scale, such as gender or color.
In summary, statement 1 is correct, statement 2 is incorrect, and statement 3 is possible.
