Information About Data Cleaning And Data Services

Data cleaning in Santa Rosa CA at NW Database ServicesInterval Vs. Ratio Data

Interval data can also be measured along a continuum. This is where each point on the scale is equal in distance. Example: The difference between 30 degrees C and 31 degrees C equals the difference between 99 degrees and 100 degrees. Interval data does not have a true or meaningful zero value. Temperature is an example. A temperature of zero does not necessarily mean there is no temperature. It just means it is extremely cold.

In terms of equally spaced points on the scale, ratio data is similar to interval data. However, unlike interval data, ratio has a true zero. Ratio data is weight in grams. The difference between 20 and 21 grams equals the difference between 8 or 9 grams. If something weighs zero grams it really does weigh nothing.

Quantitative data can be further broken down into different types, beyond the distinction between continuous and discrete data.

Measurements: These data are used to measure physical objects. Before ordering new sofas, you might measure your living space’s length and width.

Sensors: A sensor can be described as a device that detects changes in the environment and transmits this information to an electronic device, which is usually a computer. The information is then converted to numbers, which are your quantitative data. A smart temperature sensor, for example, will give you a stream of data about temperature throughout the day.

Counts: This is quantitative data that you get when you count things. You could count the number people who attended an event or how many people visited your website within a week.

Quantification of qualitative Data: When qualitative data are converted into numbers. Let’s take customer satisfaction as an example. Qualitative data would include customer satisfaction statements like “I’m really satisfied with this product”. This could be converted into quantitative data by asking customers to rate their satisfaction using a scale from 1-10.

Calculations: These are any quantitative data that is derived from mathematical calculations. For example, you might calculate your monthly final profit.

Projections: Analysts can use algorithms, artificial intelligence or “manual analysis” to project or estimate quantities. You might, for example, predict the number of sales you will make over the next quarter. This is a projection of quantitative information.

It is important to know what kind of quantitative data you are working with so that you can apply the right type of statistical analysis. Section five will examine how quantitative data are analyzed.
