Comparing Paints Brands to Analysis Variance
Author- Jagruti Raju Rathod
Introduction
Paint is any pigmented liquid, liquefiable, or solid mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, colour, or provide texture to objects. Paint can be made or purchased in many colours and in many different types, such as watercolour or synthetic. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. Most paints are either oil-based or water-based and each have distinct characteristics. For one, it is illegal in most municipalities to discard oil-based paint down household drains or sewers. Clean up solvents are also different for water-based paint than they are for oil-based paint. Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted. Usually the object being painted must be over 10 °C, although some manufacturers of external paints/primers claim they can be applied when temperatures are as low as 2 °C.
Objective
To compare Asian, Burger, Dulux, Royale and figure out if anyone is different.
Literature review
1.Image on painting
Ms Dipa Teraiya, Mrs Bhakti Solanki state that he main goal of the In painting algorithm is to modify the damaged region in an image in such a way that the in painted region is undetectable to the ordinary observers who are not familiar with the original image. Image in painting is an art of missing value or a data in an image. The purpose of image in painting is to reconstruct missing regions which is visible for human eyes. Image in painting is the process of reconstructing lost part of images based on the background information. This proposed work presents a brief survey of different image in painting techniques and comparative study of these techniques. In this paper we provide a review of different techniques used for image In painting. We discuss different in painting techniques like image PDE based image in painting, Exemplar based image in painting, Total Variation, and texture synthesis based image in painting.

2.Customers satisfaction
As per Kotler(2003) satisfactions is a persons feelings of pleasure or disappointment resulting from comparing a products perceived performance (or out come) in relation to his or her expectations. The satisfaction judgement is related to all the experiences made with a certain business concerning its given products, the sales process, and the after- sale service. Whether the customer is satisfied after purchase also depends on the offers performance in relation to the customers expectation. Customers from their expectation from past buying in experience, competitors information and promises.

Data collection
I choose four paints brands on which I will make my analysis. Then I made a google form asking them to rate them on a 1 to 10 scale. The form was shared with the 30 people and their feedback was then collected in an Excel Sheet. The data was analysed by the ANOVA (Single Factor) method. By analysing the values we came to the conclusion.

Data analysis
ANOVA: Single Factor

SUMMARY
Groups Count Sum Average Variance
Asian 30 271 9.03333 1.3436
Berger 30 274 8.4666 1.4988
Dulux 30 247 8.2333 1.9091
Royale 30 253 8.4333 1.9091

ANOVA

Source of Variation SS df MS F P-value F-crit
Between Groups 10.625 3 3.5416 2.1268 0.1005 2.6828
Within Groups 193.1666 116 1.6652
Total 203.7916 119

Conclusion
The calculated value of F value is 2.1268 at 0.05 level of significance and the tabulated value of F value is 2.1268 at 0.05 level of significance, therefore calculated value of F is greater than the tabulated F value hence we reject the null hypothesis and accept the alternative hypothesis that means we can conclude there is a significant difference in the mean.
