This graph compares the total cost of attending educational institutions in Texas. A graph titled The Cost of Post-Secondary Education in Texas from 2012 to 2013 has the type of school on the x-axis and yearly cost in thousands of dollars on the y-axis. Public 4-year university is 21,000, and private 4-year is 34,000. Public community college is 15,000, and private community college is 17,000. Technical school is 15,000.

The graph demonstrates that the cost at private and public

technical schools greatly varies.
vocational schools greatly varies.
four-year universities greatly varies.
community colleges greatly varies.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
