- The shoe size is an integer (discrete), but the underlying measurement is the length of the foot, which is measured data (continuous). Even half sizes are still not real measurements, but whole numbers, because there is nothing between size 8 and 8 1/2.
What kind of variable is shoe size?
Shoe size is also a discrete random variable. Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values, which can be any number in an interval. For example, a person’s (exact) weight is a continuous random variable.
Is the shoe size interval data?
Then he realized that shoe size is an interval variable. … An interval variable has a defined interval between values, but has no zero point. In terms of shoe sizes, we can say that the difference between shoe size 8 and shoe size 7 is equal to the difference between shoe size 2 and shoe size 3.
How do you know if something is discrete or continuous?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained through measurement. A random variable is a variable whose value is the numerical result of a random phenomenon. A discrete random variable X has a countable number of possible values.
Is the size quantitative or categorical?
Quantitative data is information about quantities, that is, information that can be measured and written in numbers. Some examples of quantitative data are your height, shoe size, and nail length. Speaking of which, it might be time to call Guinness.
Is the t-shirt size nominal or ordinal?
They don’t have numbers, nor can they be categorized – they’re just different things. Ordinal data is orderable categorical data such as shirt sizes (s/m/l/xl), flood risk (low risk/medium risk/high risk) or age (young/old medium/old).
Is the pitch discrete or continuous?
Examples of continuous variables are distance, age, and temperature. Measuring a continuous variable is limited by the methods used or by the accuracy of the measuring equipment. For example, a student’s height is a continuous variable since a student may be 1.6321748755… meters tall. 31
Does shoe size depend on height?
Shoe size is relatively proportional to height in men, especially after puberty. Tall men tend to have larger feet than average or smaller men. … Foot and shoe sizes often increase as men age. This is due to a number of factors including weight gain and wear and tear on the feet over time. 07
Is age an interval or a ratio?
A ratio scale has the first feature of the interval scale (interval), but also has a significant zero point, indicating the absence of the attribute. This allows values to be multiplied and divided. Using the definition above, age is on a ratio scale.
Is money discrete or continuous?
A continuous distribution must have an infinite number of values between $0.00 and $0.01. Money does not have this quality; there is always an indivisible unit of smaller money. And as such, money is a discrete entity.
Is age continuous or discrete?
We could be infinitely precise and use infinitely many decimals, making the age continuous. For everyday devices, however, all values less than 6 years and greater than 5 years are referred to as 5 years. We therefore use age generally as a discrete variable.
Is the shoe size categorical?
Shoe sizes are sort of a continuous measure that you can theoretically make a shoe size 11.231. But if it’s not a size 13 (or tight) it won’t fit me, so it’s a definitive measurement for all intents and purposes.
Is shoe size a categorical fact?
- The shoe size is an integer (discrete), but the underlying measurement is the length of the foot, which is measured data (continuous). Even half sizes are still not real measurements, but whole numbers, because there is nothing between size 8 and 8 1/2. 2.
