Description

Statistics for EconomistsThis first course in statistics is designed for undergraduate students. There are dozens of statistics textbooks in the market. But most of these textbooks are either pitched at a level that is too high or too low for most undergraduate students. Many use calculus and are designed for graduate students in technical fields. Others provide black box formulas without any derivations. This textbook focuses on deriving everything from first principles

This first course in statistics is designed for undergraduate students. There are dozens of statistics textbooks in the market. But most of these textbooks are either pitched at a level that is too high or too low for most undergraduate students. Many use calculus and are designed for graduate students in technical fields. Others provide black box formulas without any derivations. This textbook focuses on deriving everything from first principles without using calculus or linear algebra. It is important for students to understand why they are doing what they are doing. Otherwise students cannot distinguish meaningless results from significant results. This textbook gets to the major points quickly and is thus relatively short and very accessible.

Hold my umbrella & watch this!
Size: 100LBS, Size: 100LBS
This product does a fantastic job of keeping our umbrella perfectly vertical. We previously had an all metal one which cost over $100 and fell over all of the time. I love the fact that it can be filled with sand and water to ensure it does flip over! We opted to just use water and it is performing flawlessly! The wheels make it easy to move or they can be locked in place. The assembly was very straightforward and took about 20 minutes. I would buy another one if we need it for our second umbrella.

Great stand for portability, concerns about durability
Size: 155LBS
This is great and lightweight for easy maneuverability when not filled. It is extremely sturdy when filled and the locks on the wheels keep it in place. I use this with a Purple umbrella and it's great. My one complaint is that the umbrella has developed a bit of a lean after several months of use so I don't think this will hold up in the long run.

Great Service and company
Size: 100LBS
This umbrella stand we purchased does the job our previous heavy metal stands could not do. It stands up to high winds where we were forever standing our umbrella back up with our old stands. When I filled the stand base up with water and sand I accidently locked one of the wheels and pushed it from my truck to our pool patio and ground one of the wheels down to its rim. I messaged Fruiteam asking if I could purchase a new wheel and they sent me a set of 4 no charge. Great product and great customer service!

Perfect! Easy, convenient, definitely recommend
Size: 100LBS, Size: 100LBS
I am so glad I found this base that I can just fill with water. After screwing on the wheels, I used my garden hose to fill it with water and put my 1.5 inch diameter umbrella in and tightened it. Easy peasy. I love that it rolls and I can move it wherever I want, and also lock two of the wheels if needed. Definitely would recommend this one!

Size: 100LBS
Happy with my purchase. Sturdy well built, love that it has wheels makes it easy to move around and wheels lock in place. I choose to fill it with sand and water as it gets really windy where we live this will prevent my umbrella flying to the neighbors house again 😅
