analysis of variance (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent variables; 2. what are the interactions among the dependent variables and 3. among the independent variables.[1] Where sums of squares appear in univariate analysis of variance‚ in multivariate analysis of variance certain positive-definite

to explain what types of rocks will dissolve in water. They need to use the same rocks from the backyard. You can’t compare different types of rocks. Just because it appears to shrink doesn’t mean it actually did. You need real data of what the mass of the rocks were before the rainstorm. 2. Using what Christopher and Kate have already observed‚ suggest a possible hypothesis regarding how the mass of a rock changes when placed in water. Identify the independent and dependent variables. If the rock

THEORETICAL FRAMEWORK A theoretical framework is a conceptual model of how one theorizes or makes logical sense of the relationship among the several factors that have been identified as important to the research problem concerned. To put it simply a theoretical framework involves identifying the network of relationship among the variables considered important to the study .It provides the conceptual foundation to proceed further with the research. The theory is developed based on the documentation

nominal GDP data. CH-8.Ex-2. Key Question Suppose an economy’s real GDP is $30‚000 in year 1 and $31‚200 in year 2. What is the growth rate of its real GDP? Assume that population is 100 in year 1 and 102 in year 2. What is the growth rate of GDP per capita? CH-8.EX-11. Key Question If the CPI was 110 last year and is 121 this year‚ what is this year’s rate of inflation? What is the “rule of 70”? How long would it take for the price level to double if inflation persisted at (a) 2‚ (b) 5‚ and

WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance‚ or‚ equivalently‚ a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We

What is the biological significance of having two different types of terminators in transcription? Transcription in prokaryotes is terminated by factors called rho-dependent and rho-independent terminators; Rho is a ring-shaped protein and is the main factor required for termination (Leland‚ 2010). The rho-dependent and rho-independent terminators play a major role in the separation of an RNA transcript from the DNA template which signifies the end of transcription. However‚ the exact process is

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will
