Comparative study on refrigerators sold in Turkey

Abstract

As modernization continues, the lifestyle in domestic settings had become more entwined in the usage of gadgets and appliances. Among the appliances, refrigerators has grown to become one of the most useful in food storage in most countries. It has already become among the key features of any kitchen and hence, an integral part of the home appliances market. This paper presents a comparison of some refrigerators commercially sold in Turkey. The parameters included were brand, type of refrigerator, capacity, price and star ratings. Based on the Pearson correlation price was more strongly positively related to capacity p<0.001, than to defrosting type p<0.01, or to door type p<0.01. Free frost types are more likely to be of higher prices than direct cool types. The double door type is more likely to be of higher prices than the single. Furthermore, ANOVA on brand and defrosting type has shown that there is a significant difference among the five brands of refrigerator on defrosting type, p<0.01. Post-host testing revealed significant differences between group of BRAND1 and BRAND3, having more of free frost type of defrosting than BRAND5, BRAND4, and BRAND2. However, ANOVA on brand and price and ANOVA on brand and star ratings revealed that there are no differences among the five brands of refrigerator on price and on star rating which means that price and star rating are more dependent on capacity, door type and defrosting type regardless of the brand of the refrigerators.
