We reviewed the remaining parts of CODAP assignments. And then,
1. Pose a Question
2. Collect Data
3. Analyze Data
4. Interpret Result
What is meanin of Inference?
‘Our work with students in learning statistics should be grounded in using the four phases of a statistical investigation (pose questions, collect data, analyze data, and interpret results). While these phases are often done in that order, they can also be non-linear and cyclic in nature. For example, one may start with a set of data that has already been collected and do some preliminary exploration of the data, often called exploratory data analysis (EDA). From what is noticed, we may then pose a targeted question involving only a few variables in the dataset. From there, data for the variables of interest would be selected, and proceed to the analysis and interpretation phase. Additionally, interpretations may spark new or additional questions to require further investigation with data at hand, or require additional data collection. Depending on the question posed (either initially or one that emerges during data analysis), the interpretation phase may include descriptive statements about what the data tells us, or may include wonderings or claims about what the data tells us about some larger population, process, or model. As students progress in their sophistication, their claims should shift from only being about the data at hand towards looking beyond the data to make claims about a larger collection, entire population, or a process and model. When making a claim beyond data, one uses the evidence known to them (through data) and reasoning to infer something about which you do not have explicit knowledge’
In statistical research, the sample should be correct. For example, which team do support the people living in Kadıköy? The conclusion is not covered for all Turkey.
