What is a categorical variable

Mathematics
1 answer:
Fantom [35]3 years ago
5 0

It's a variable that deals with various labels, rather than the usual type of numeric variable you may be used to.

One example of a categorical variable is color. You could have red, green, blue, yellow, and orange as the five choices for your categorical variable. Each color is a label or category.

This is an example of a qualitative variable. We don't have any numeric data attached to color. They're simply names or labels. In contrast, a quantitative variable is something like a person's height since a number is attached here (more specifically its a continuous quantitative variable).

1)

\dfrac{3}{4}  + 5 -  \dfrac{1}{2}  = \dfrac{3}{4}  +  \dfrac{20}{4} -  \dfrac{2}{4}  =  \dfrac{21}{4}  = 5 \dfrac{1}{4}

2)

\dfrac{2}{3}  +  {2}^{3}  -  \dfrac{1}{3}  =  \dfrac{2}{3}  +  \dfrac{24}{3}  -  \dfrac{1}{3}  =  \dfrac{25}{3}  = 8 \dfrac{1}{3}

3)

- 15 + 6x - 19 - 20x =  - 14x - 34

4)

- 7x - 2 - 9y + 10x = 3x - 9y - 2

5)

14 + x = 18 \\ x = 18 - 14 \\ x = 4

6)

- 5x =  - 15 \\ x =  - 15 \div ( - 5) \\ x = 3

7)

- 2x + 8 = 18 \\  - 2x = 18 - 8 \\  - 2x = 10 \\ x = 10 \div ( - 2) \\ x =  - 5

8)

3x + 18 - 8x =  - 17 \\ 3x - 8x =  - 17 - 18 \\  - 5x =  - 35 \\ x =  - 35 \div ( - 5) \\ x = 7

Kyra has a rock collection.When she puts her rocks into 2 equal piles,there are no rocks left over.When she puts her rocks into
liubo4ka [24]

any multiple of 12

Since 2, 3 and 4 divide exactly into the number of rocks

We are looking for the common multiples of 2, 3 and 4

2 × 3 × 4 = 24 is possible but dividing by 2 gives 12 the lowest common multiple

Any multiple of 12 gives a possible number of rocks.
