There are two types of quantitative data, which is also referred to as numeric data: continuous and discrete. * Shows how often something occurs. Maximum or Minimum value. First, we tailor it to our … Both of these are employed in scientific analysis of data and both are equally important for the student of statistics. If the data is non-normal, non-parametric tests should be used. It involves applying math to analyze the probability of some event occurring, where specifically the only data we compute on is prior data. Meristic or discretevariables are generally counts and can take on only discrete values. Quantitative data, qualitative data, nominal data, ordinal data, interval data and ratio data - we explain them all 2.

The independent variable is the one that is computed in research to view the impact of dependent variables. Numerical measurements exist in two forms, Meristic and continuous, and may present themselves in three kinds of scale: interval, ratio and circular. Standard deviation (a … They can make sense of the information. Primary data has several advantages. Qualitative means you can't, and it's not numerical (think quality- categorical data instead). This type of graph is … When we obtain data directly from individuals, objects or processes, we refer to it as primary data. Normally they are represented by natural numbers. This allows social scientists to view patterns. Ø The scientific investigations involve observations on variables.

Qualitative data are often termed categorical data. … Each type of investigation involves a different approach to collecting data. Commonly used summaries: Average value. The information types here include central tendency numbers like mean, median, and mode, along with other statistics … Statistical data is gathered using a sample procedure or other method. A histogram in another kind of graph that uses bars in its display. He wants to know the reason behind smart guys and failure guys. Measures of Frequency: * Count, Percent, Frequency. If you're behind a … Simple, right? … The last half of the course will cover inferential statistics. For example, A manager asks 100 employees to complete a project. Frequency Statistics is the type of stats that most people think about when they hear the word “probability”.

The two main branches of statistics are descriptive statistics and inferential statistics. In statistics, it is often used … There's one more distinction we should get straight before moving on to the actual data types, and it has to do with quantitative (numbers) data: discrete vs. continuous data.
