Introduction
A mobile phone is a wireless handheld device that allows users to make and receive calls. While the earliest generation of mobile phones could only make and receive calls, today’s mobile phones do a lot more, accommodating web browsers, games, cameras, video players and navigational systems.
Also, while mobile phones used to be mainly known as “cell phones” or cellular phones, today’s mobile phones are more commonly called “smartphones” because of all of the extra voice and data services that they offer. There are multiple mobile brands available in the market today out of which below five brands have been considered for the comparison.
1 Vivo
2 Samsung
3 OnePlus
4 Iphone
5 Oppo
Objective:
To compare five mobile brands using one-way ANOVA technique.

OnePlus phones are the only Android smartphones that come with an iPhone-style silent switch, making it easy to quickly switch the phone to silent and vibrate-only. OnePlus phones also come with their own charging brick technology that keeps the heat that usually comes with charging in the brick itself.

Data Collection
30 Students have been surveyed by creating a Google Form and requesting them to rate the Mobile brands. Rating was on Linear Scale (1 to 5 scale, 1 being Lowest and 5 being Highest). The response data was then exported in Excel using Google Forms and further analysis were carried out. Using Excel’s Data Analysis with Single Factor Anova tool, below analysis were recorded.
Data Analysis:
H0: All five mobile phone are same.
H1: Any one of the mobile phone is different.
ONE WAY ANNOVA ANOVA Table:
Source of Variation, SS, df, MS, F, P-value, F-Crib
Between Groups, 34.5, 4, 8.64, 5.830, 0.000223, 2.435
Within Groups, 215, 145, 1.482
Total, 249.5733
Conclusion
Since p value is less than 0.05 except h1 (alternate hypothesis) we can conclude any one of the mobile phones is different alternatively since as F (5.83 ) is greater than F critical ( 2.43) we can conclude any one of the mobile phone is different
