11.30 fcat scores and poverty. in the state of florida, elemen- tary school performance is based on the average score obtained by students on a standardized exam called the florida comprehensive assessment test (fcat). an analysis of the link between fcat scores and sociodemo- graphic factors was published in the journal of educational and behavioral statistics (spring 2004). data on average math and reading fcat scores of third graders, as well as the percentage of students below the poverty level, for a sample of 22 florida elementary schools are listed in the table on p. 629.

The study of data collection, analysis, presentation, and interpretation is known as statistics. Much of the early push for the subject of statistics came from government needs on census in addition to data on a range of economic operations. The current requirement to convert vast volumes of data accessible in many applied disciplines into valuable information has driven both theoretical and practical breakthroughs in statistics.

The facts and statistics that are gathered, standardized, and condensed for presentation and interpretation are known as data. The two types of data are quantitative and qualitative, respectively. Quantitative data quantify how much or how many of something exists, whereas qualitative data offer labels or names for groups of similar objects.

How to solve?

We need to determine whether the math core or the reading score better predicts the percentage of students below the poverty level.

The standard error s=11.2996s=11.2996 for the math scores is less than the standard error s=14.4128s=14.4128 for the reading scores, thus the math scores will result in better prediction.
