Question

10 variables cuantitativas porfa

Answer 1

En estadística, las variables cuantitativas son aquellas que emplean cantidades numéricas para expresarse, esto es, que se pueden medir. De ellas existen dos tipos, las variables cuantitativas discretas y las variables cuantitativas continuas.

 

Las variables cuantitativas discretas son aquellas que obedecen a una cantidad numérica exacta, que puede tomar únicamente valores enteros y que sólo puede tomar valores dentro de un conjunto definido. En este caso, 5 ejemplos de variables cuantitativas discretas serían:

·         El número de hijos en una familia (1,2,3,4..)

·         El número de carros que hay en un estacionamiento (…10,11,12,13,14..)

·          The number of employees working in a factory (... 100,101,102,103 ..)

·          The number of cows on a farm (.5,6,7,8,9 ..)

·          The number of fingers that a person has on the hands (1,2,3,4,5,6,7,8,9,10)

Note that for all cases the values ​​must be exact and integers. That is, a family can not have 1.3 children, nor in a parking can there be 12.6 carts, nor in a farm 6.8 cows.

 

For their part,  Continuous Quantitative Variables  are numerical variables that allow decimal expressions because they can take any real value within a range (that is, there are infinite possibilities). In this case, 5 examples of continuous quantitative variables would be:  

·          The weight of a person (0-200 kg)

·          The time it takes to travel (0 hours - 36 hours)

·          The distance of a road (0 kilometers - 4000 kilometers)

·          The price of supermarket items (0 pesos - 4000 pesos)

·          The speed of an airplane (0 km / h - 900 km / h)

Note that in all cases there are infinite values ​​in the interval because the values ​​can be expressed in that way. For example, a person can weigh 76.78 kilograms, as well as the distance on a road can exactly be 234.58 kilometers and the price of an item in the supermarket can be 27.33 pesos.

 

I hope that is your help!
