Working on data is crucial because we need to figure out what kind of data it is and how to use it to get valuable output out of it. Also, the value of 0 is arbitrary because negative values of temperature do exist which makes the Celsius/Fahrenheit temperature scale a classic example of an interval scale. Data at the ordinal level of measurement are quantitative or qualitative. Of course, it has to be a story, data scientists are superb storytellers after all! Range, standard deviation, and variance are all measures of variability within your dataset. One of the most important and basic step in learning Statistics is understanding the levels of measurement for the variables. There are occasions when you will have some control over the measurement scale. Ordinal data mixes numerical and categorical data. This data is also considered Ordinal data. The number of car accidents at an intersection is an example of a discrete random variable that can take on a countable infinite number of values (there is no fixed upper limit to the count). However, a temperature of 10 degrees C should not be considered twice as hot as 5 degrees C. If it were, a conflict would be created because 10 degrees C is 50 degrees F and 5 degrees C is 41 degrees F. Clearly, 50 degrees is not twice 41 degrees. So, Im a wannabe data alchemist(more popularly known as data scientist). Eg: Shoes can be categorized based on type (sports, casual, others) or color (black, brown, others).

Answer (1 of 4): Here is simple explanation of the main types of variables- Continuous- Can take any values between a permitted range. Note the differences between adjacent categories do not necessarily have the same meaning. also called the categorical variable scale, is defined as a scale used for labeling variables into distinct classifications and doesnt involve a quantitative value or order. Ordinal scale has all its variables in a specific order, beyond just naming them. The final descriptive you can use for ordinal data is variability. Each scale builds upon the last, meaning that each scale not only "ticks the same boxes" as the previous scale, but also adds another level of precision. Each level of measurement scale has specific properties that determine the various use of statistical analysis. This data is so important for us that it becomes important to handle and store it properly, without any error. These values puts a person into a particular category and there is also a defined relative ordering between the classes like upper class > midde class > lower class. What are some ratio and interval examples? The discrete data are countable and have finite values; their subdivision is not possible. Another counter example is pH. Just like the interval scale, the ratio scale is a quantitative level of measurement with equal intervals between each point. What are some illustrations of the ordinal scale?
