multiple data series

A survey was conducted on the length of the names of the students in a class. What type of graph would be most appropriate to show the range of the data? => scatter plot or multiple bar graph or circle graph or line plot..

Which time series graphs represents the percentage change in the number of chronic patients (cases) in a major hospital over the years? The data is given as: Year 1999 2000 2001 2002 2003 2004 Chronic patients (%) 2.3% 2.4% 1.8% 1.9% 2.0% 1.7% => both Graph 1 and Graph 2 or Grap..

The formula for the F test used to test the significance of the multiple correlation coefficient R using n the number of data sets and k the number of independent variables and d.f. N = n - k , d.f. D = n - k - 1 is => R 2 ( n - k ) 1 - R 2 ( n - k - 1 ) or 1 - R 2 ( n - k ) R 2..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, relations and ..

>Simple reactions are those, which involve a single elementary reaction. The rate law can be written from the stoichiometry of the chemical equation. One such reaction is the gas phase reaction of ozone (O 3 ) with nitric oxide (NO). This bimolecular reaction exhibits second order kinetics. However..

>Darwin believed that tiny particles called pangenes are formed in the different parts of the body, which migrate to the gametes. The blending theory on inheritance became replaced by the particulate theory of inheritance due to the contributions made by John Gregor Mendel (1822-1884). Mendel condu..

Multiple approaches to solve problems Techniques to study patterns and analyze data Problems related to personal income and credit Problems related to financial planning Transformations, symmetr..

Carbon monoxide (CO): 12 parts by mass of carbon combines with 16 parts by mass of oxygen. Carbon dioxide (CO 2 ): 12 parts by mass of carbon combines with 32 parts by mass of oxygen. Ratio of the masses of oxygen that combines with a fixed mass of carbon (12 parts) 16: 32 or 1: 2 For example, hyd..

A coaxial cable consists of an inner conductor and an outer conductor, separated by a dielectric insulating material. The inner conductor is made of a copper wire encased inside the dielectric material. As for the outer conductor, it is made of copper, tinned copper, or copper-coated steel. Typica..

Linear equations/inequalities Monomials and polynomials Factoring second and third degree polynomials Rational expressions/functions Quadratic equations Quadratic functions Exponents, factors, variation, exponential growth/decay Hypothesis, counterexamples Correlation for data ..
