How do the three graphs below show this result could have been predicted? b. We had the data-but not all the data. What Rule is this an example of?Explanation / Answer
After analyzing the three graphs we can say that there is a good positive correleation between week and frequency in the first graph, good negative correlation between week and frequency in second graph and neutral correlation in the third graph.
"We had data but not all the data" - In Statistics this can be explained in either of two ways. Either we can say that the available data is a sample data taken from an entire population. So we have a representative sample of the entire population.
On the other other we can say that this is a censored data ( left or right ). In this case, some data is available but some data is missing.
