(a)

To determine

To explain:To explain whether the number of injuries sustained in fall is a Discrete or a numerical variable.

Expert Solution

Answer

It is a discrete variable.

Explanation of Solution

A variable is numerical when measurements of individuals are quantitative and feature magnitude. These variables are numbers. A numerical variable gives a dimension or a number, a numerical meaning. A continuous variable are those whose price is taking with the aid of measuring. A discrete variable is those whose price is taking with the aid of counting.Number of injuries sustained in a fall is discrete variable. Discrete numerical data are available indivisible units. Discrete numerical data are often analysed as though they were continuous, if there are many feasible values.It has a finite amount of possible values that do not have an inherent order.

(b)

To determine

To explain:To explain whether the fractions of the birds which were available in a bigger sample infected with the flu virus is a discrete or a numerical variable.

Expert Solution

Answer

It is a discrete variable.

Explanation of Solution

A variable is numerical whilst measurements of people are quantitative and have magnitude. These variables are numbers. A numerical variable gives a dimension or number, a numerical meaning. A continuous variable are those whose cost is taking with the aid of measuring. A discrete variable is those whose fee is taking with the useful resource of measuring. Fraction of birds in a big pattern infected with avian flu virus is achieved by countingis discrete variable. Discrete numerical facts come in indivisible units. Discrete numerical variables are often analysed as though they were continuous, if there may be many viable values. It has a finite quantity of possible values that don’t have an inherent order.

(c)

To determine

To explain:To explain whether the amount of crimes done by an individual who was randomly sampled is a discrete or a numerical variable.

Expert Solution

Answer

It is a discrete variable.

Explanation of Solution

A variable is numerical while measurements of individuals are quantitative and have magnitude. These variables are numbers. A numerical variable offers a dimension or variety, a numerical meaning. A continuous variable are the ones whose price is taking with the resource of measuring. A discrete variable are the once whose rate is taking with the aid of counting. Amount of crimes completed by means of a randomly sampled character is completed by using counting is discrete variable. Discrete numerical records come in indivisible units. Discrete numerical variables are often analysed as even though they were continuous, if there’s a huge variety of possible values. It has a finite amount of feasible values that don’t have an inherent order.

(d)

To determine

To explain: To explain whether Log values belonging to the mass of the body is a discrete or a numerical variable.

Expert Solution

Answer

It is a continuous variable.

Explanation of Solution

A variable is numerical while measurements of individuals are quantitative and have magnitude. These variables are numbers. A numerical variable offers a dimension or variety, a numerical meaning. Continuous variable is inside the maximum minimum value. Range of values are gift in non-stop variables.Body mass log valuesis a continuous variable.Continuous numerical statistics can tackle any real-quantity price within a few range.Numerical variable is expressed as a number.Between any two values of a continuous variable, a limitless form of other values are possible.In practice, non-stop information are rounded to a predetermined range of digits, set for convenience or by the restriction of the instrument used to take the measurements.
