Is birth month nominal or ordinal?
Month should be considered qualitative nominal data..
Is age nominal or ordinal?
Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is a used to collect nominal data while “Are you the first born or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.
How can I measure 1 kg without scales?
If you are willing to use a metre ruler to measure lengths, you can use this technique: The density of water is 1000 kg/m^3, or more accurately 0.998 207 1 g/cm^3 at 20 °C (it varies very slightly with temperature). If you create a volume of water of 1000 cm^3 with a cube of lengths 10 cm, you will have 1 kg of water.
What type of data is age?
Mondal suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.
Why do we measure weight in kg?
When we use kilograms to measure weight, we are actually referring to kgf or kilogram-force. From Wikipedia: One kilogram-force is equal to the magnitude of the force exerted by one kilogram of mass in a 9.80665 m/s2 gravitational field. In other words, the weight(force) of one kg is equal to one kgf, or 9.8N.
What type of data is IQ score?
An IQ (Intelligence Quotient) score from a standardized test of intelligences is a good example of an interval scale score. IQ scores are derived from a lengthy testing process that requires the participant to complete a number of cognitive tasks.
Is weight nominal or ordinal?
When working with ratio variables, but not interval variables, the ratio of two measurements has a meaningful interpretation. For example, because weight is a ratio variable, a weight of 4 grams is twice as heavy as a weight of 2 grams.
What type of data is weight in kg?
An example of numeric continuous data is weight – i.e. one does not have to be exactly 65 or 70 kg; one may easily be 67.5567kg.
How can data be measured?
Data that are counted or measured using a numerically defined method are called numerical (quantitative). Discrete data arise from observations that can only take certain numerical values, usually counts such as number of children or number of patients attending a clinic in a year.
What are the 4 measurement scales?
Scales of measurement refer to ways in which variables/numbers are defined and categorized. Each scale of measurement has certain properties which in turn determines the appropriateness for use of certain statistical analyses. The four scales of measurement are nominal, ordinal, interval, and ratio.
Is age categorical or numerical?
In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old.
What type of variable is weight?
A continuous variable can take on any score or value within a measurement scale. In addition, the difference between each of the values has a real meaning. Familiar types of continuous variables are income, temperature, height, weight, and distance. There are two main types of continuous variables: interval and ratio.
What level of data is weight?
Ratio Level: Eg: Weight of a person. It has a real zero point, i.e zero weight means that the person has no weight. Also, we can add, subtract, multiply and divide weights at the real scale for comparisons.
