Hypothesis: My hypothesis is the most expensive battery on the market would last the longest and be the most effective.
My hypothesis is not based entirely on scientific information. Batteries are in a very competitive market, with so many different brands and prices. I chose to use AA, the most popular size of battery. Price is important to think about when choosing between brands. I think the brand that is the most expensive will be of higher quality and last longer.
Conclusion: My hypothesis was partially correct. Energizer, the most expensive battery, did last the longest. But the battery that came in second place, Everready, was the most cost effective.
