In Statistics, we are learning about data collection. Statistics is the science of collecting , organizing, analyzing and interpreting data in order to make decisions. Data consists of information coming from observations , counts , measurements or responses. This week, we are learning about the four methods to collecting data. The four methods are survey use, simulation use of mathematics / physical model , observation study and experiment. I am not too familiar with these methods so reading my notes over and over will help me get a better understanding. The first method is using a survey which is an investigation of one or more traits of a population. The investigation is done through questioning and interviewing in person, phone or mail. The second method is simulation use of mathematics which allows researchers to study situations that are impractical or too dangerous to create in real life. The third method is observation study which is when researchers observe and measure characteristics of the sample group of interest but, do not change the conditions of the group. The last method is experiment which is when members of the sample group and responses are observed. I know that towards the end of this week Mr. Rich will test us on this information.
