Math 143 – ANOVA Analysis of Variance (ANOVA) 1 Recall‚ when we wanted to compare two population means‚ we used the 2-sample t procedures . Now let’s expand this to compare k ≥ 3 population means. As with the t-test‚ we can graphically get an idea of what is going on by looking at side-by-side boxplots. (See Example 12.3‚ p. 748‚ along with Figure 12.3‚ p. 749.) 1 Basic ANOVA concepts 1.1 The Setting Generally‚ we are considering a quantitative response variable as it relates to one or

Science claims that by the end of the century the long term impacts in the surface of earth will have inevitable irreversible consequences (Hansen‚ 13). The most discussed debate nowadays‚ as a solution for CO2 emissions and consequently global warming‚ is the shift

Period G Interspecific and Intraspecific Plant Competition Abstract A study was conducted to address the problem of interspecific and intraspecific competition among wheat and mustard plants. It was hypothesized that increasing the plant density‚ and therefore increasing intraspecific competition‚ would negatively impact the plant biomass. It was also hypothesized that interspecific competition would have a stronger negative effect on the plant biomasses. This was tested by planting varying

Purpose: The purpose of this lab is to find the amount of blue dye #1 in the blueberry pomegranate gatorade. Procedure: We created dilutions using stock solution(10mL stock/0 mL water‚ 8mL/2mL‚ 6mL/4mL‚4mL/6mL‚ 3mL/7mL‚ 2mL/8mL‚1mL/9mL‚ 0mL/0mL). Before we put each dilution in the SPEC 20‚ we put water in a cuvette and put it in the SPEC 20 so we could zero out the percent transmittance. We collected the percent transmittance of each dilution using the SPEC20 with a wavelength of 630nm.
