Summary on Statistics
Chapter one summary
The use of statistics is research is noted in this chapter. It reveals that statistical procedure could be segregated into two section and they are descriptive and inferential. In analyzing both descriptive statistics does exactly what it says, it describes the set of data. The problem is presented and descriptive statistical basically describes what the data has to say about the same issue. However inferential statistics main goal is making predictions or inferences about a population from observations and analyses of a sample. That is, we can take the results of an analysis using a sample and can generalize it to the larger population that the sample represents. (Howelll, 2011) Also stated that a population is referred to as a “complete set of events in which you are interested. Samples was defined as “Set of actual observations; subset of a population.” A statistic is when we measure that is based on a sample; the parameter is described as the matching measure of the entire surveyed population. It shows the effect and the importance of each in the statistics, differences versus relationship, was also mentioned in chapter one and defined as question that are being asked in different ways to see the link between them.
Two types of data were presented and they were numerical data and categorical data. Numerical data is categorized into two parts, the first being measurement data, this is where event or objects are being measured and categorical data, gives a specific count of what happens.

    It is known that there are two data types that are utilized to evaluate and draw meaningful conclusions through statistics, population and sample data. These two data types are utilized to formulate end conclusions of data that is to be collected and data that is to be reviewed. The description of population data can best be explained, as the complete collection of all data that is to be queried/collected and reviewed. Sample data, a subset of population data, is the partial collection and review of all data that is to be queried. The relationship of these two data types is simple; sample data is represented as a reflection of the population data and shares a common goal in this comparison through statistics. This can also either be represented as a part or as a whole of all data being evaluated. However we tend to utilize sample data more often than population data primarily as a result that sample data is utilized to formulate a coherent approach to drawing meaningful conclusions about the population. We utilize this through random sampling of population data to gather and make an assumption based on the population. This can kind of draw the conclusion that sample data and population data go hand in hand.…
