College-Readiness in Reading: Differences by Accountability Rating

Research question

The following research question was addressed in this study:

  • What is the difference in college-readiness reading rates between Texas high school campuses as a function of accountability rating?

Results

Prior to conducting an inferential statistical procedure, checks for normality of data were conducted. With respect to the distribution of scores underlying college-readiness rates in reading, the standardized skewness coefficients (i.e., skewness divided by the standard error of skewness) and the standardized kurtosis coefficients (i.e., kurtosis divided by the standard error of kurtosis) revealed no serious departures from normality for the variable of interest. Readers are directed to the Appendix where the skewness and kurtosis values are present. By calculating the standardized coefficients, the reader can ascertain that all of the standardized coefficients were within the +/-3 range (Onwuegbuzie&Daniel, 2002). Because these standardized coefficients were indicative of normally distributed data, use of a parametric Analysis of Variance (ANOVA) procedure was justified.

Regarding the extent to which differences might be present in college-readiness rates in reading as a function of school accountability rating (i.e., Exemplary, Academically Recognized, Academically Acceptable, and Academically Unacceptable), an ANOVA was calculated. This ANOVA revealed a statistically significant difference, F (3, 1228) = 97.45, p <.001, n 2 = .19. The effect size for this statistically significant difference was large (Cohen, 1988). Scheffe` post hoc procedures revealed that differences were present in college-readiness rates in reading between each pair of accountability ratings. As evidenced in Table 1, college-readiness rates in reading were highest at Exemplary high schools, followed by Academically Recognized high schools. As the accountability rating became poorer, college-readiness rates in reading were statistically significantly lower. Readers are directed to Table 1 for the descriptive statistics for college-readiness rates in reading by school accountability rating.

are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
