“…The variance of original observations can be suggested to be a constant for all values of the response from the random scattering of the points instead of funnel-shaped pattern [19,20]. They also indicate the lack of need for transformation.…”

“…There is need to assess the outliers (i.e., The data points that lied far away from the true regression line). Data recording error or region of the independent factor variable space where the fitted model is a poor approximation to the true response surface can be determined using them [19]. In addition to that, estimates of regression coefficients can be distorted.…”

“…The following scheme (Figure 1) illustrates a simple sol-gel route for metal oxide synthesis. Zhang et al (2003) used the sol-gel route to prepare hematite nanoparticles starting from a 1:1.1 ratio of Fe(NO 3 ) 3 and citric acid. Fe(NO 3 ) 3 was dissolved in water followed by citric acid.…”

“…The researchers concluded that with increase in the annealing temperature maghemite changes to hematite and particle size also increases (Zhang et al, 2003). Pawar et al (2012) used similar method to synthesize hematite nanoparticles with slight modification and tested the effect of calcination temperatures on the Brunauer, Emmett and Teller (BET) surface area and photocatalytic properties of the materials.…”

“…The preparation started with the suspension of colloidal ferric nitrate nine-hydrate (Fe(NO 3 ) 3 .9H 2 O) particles (200 ml) and mono hydrated citric acid (C 6 H 8 O 7 .H 2 O) (0.1 and 0.2 M concentrations) in 800 ml of distilled water following the same procedure reported elsewhere [22]. Citric acid is commonly used because of its effects in the formation, growth and shape of iron oxides nanostructures [23].…”
