How to use the table choose function
In a table (using Excel as an example), the grammar of the ChoOSe function is ChoOSe(index_num, value1, [value2],...). Its function was to select a value from a list of up to 254 values based on the index number. The following are some typical usages: ** 1. Transform date into quarter ** If column A is date data, to convert the date to the corresponding quarter, you can enter the formula in the corresponding cell (such as column B):= Choice (Month(A2),"1st quarter","1st quarter","1st quarter","2nd quarter","2nd quarter","3rd quarter","3rd quarter","4th quarter"). Take cell A2 as an example. Months (A2) will get the month number of the date in cell A2. This month number will be used as the index number, and the corresponding quarter string will be selected according to the settings in the formula. ** 2. Replacing the nesting of the IF function to determine the level ** If there is a comparison table of scores and grades (such as cells E1:F6), to determine the score level of each student in column A (the results are placed in column C), you can enter the formula in cell C2:=Choose((B2>=0)+(B2>=60)+(B2>=70)+(B2>=80)+(B2>=90),"E","D","C","B","A"). In this formula, the calculation result of (B2>=0)+(B2>=60)+(B2>=70)+(B2>=80)+(B2>=90) was used as the index number, and the corresponding level was selected according to the range of conditions that the score met. ** 3. Reverse query with the VLOOkUP function ** For example, if there was an employee information table A1:D8, one had to inquire about the employee number of a specified employee. You can enter the formula in the corresponding cell (such as G2):=VLOOkUP(F2,Choose({1,2},$B$1:$B$8,$A$1:$A$8),2,False). Here, Choise ({1,2},$B$1:$B$8,$A$1:$A$8) will generate a new array, with the B1:B8 "Name" column as the first column, and the A1:A8 "Work Number" column as the second column. Then the VLOOkUP function will use this new array as the search area to perform a reverse query. ** 4. Randomly select data from a specified range ** If you want to randomly select a name from the names in cells A2:A5, you can enter the formula in cell C2:=Choose(Randbeteen (1,4),A2,A3,A4,A5). Among them, Ran Between (1,4) would generate a random number between 1 and 4. This random number would be used as an index number to select a name from A2, A3, A4, and A5. In addition, you can also use the choose function to achieve the sum of the conditions of the region, or when you use the vlook up function to search for data and the search area is inconsistent with the usual search area, you can use the choose function to re-match the area to be found for reverse query and other operations. "Choose" was equally exciting. Everyone was welcome to read it!

How to choose a table tennis racket?
Choosing a table tennis racket could be considered from the following aspects: ** 1. Choose based on your basic skills ** 1. ** Beginner (about one year of practice)** - Don't pursue high-end rackets too much. Beginners felt unfamiliar with the ball, and it was difficult to penetrate the rubber. The performance of the high-end bottom plate could not be fully utilized, so there was no need to choose a racket that was too expensive. 2. ** A player with a few years of basic skills ** - You can use the Advanced Slab, but you don't have to choose an expensive one. The focus of this stage was to pursue advanced techniques, the combination of force and friction. If he chose a base plate that was too violent and elastic, and his own friction technique could not keep up, it would lead to an increase in mistakes. 3. ** A player with mature basic skills ** - They could choose according to their own playstyle, strength, and flexibility. This was because they had a sense of control over the power in their hands. ** 2. Choose based on technical features ** 1. ** Violent fans (self-motivated)** - A soft table tennis base should be chosen. The ball's own strength could already provide enough speed, and the bottom plate was needed to assist in creating friction and arcs. If the bottom plate was too hard and elastic, under the situation where the player's own strength was already large, the bottom plate's additional assistance would lead to a significant increase in the error rate. 2. ** A fan who has a delicate feel and is good at holding the ball (pulling the ball and turning it, good at creating friction)** - It was recommended to choose a flexible bottom plate, but not a hard bottom plate. This would help to make use of the advantages of creating rotation. ** 3. Choose according to the type of base plate ** 1. ** No Splicing Cypress Wood Floor ** - The advantage was that the wood was not compressed and had great elasticity, but there were fewer cypress trees. 2. ** Five layers of pure wood flooring ** - It is relatively thin and light, made of five layers of wood glued and pressed together, with three vertical and two horizontal veins. When hitting the ball, there would be a vibrating feel, a clear feel, and a relatively soft ball. It was more suitable for beginners, but players who pursued a speed style were not recommended to choose it because the speed of the ball was relatively slow. Players with basic skills might think that the speed of the ball was "meaty". ** 4. Consider how to hold the racket ** 1. ** Shakehand Racquet (Shakehand)** - It was a common choice for beginners nowadays to balance the pros and cons, exert force smoothly, and hold the racket comfortably. 2. ** Penhold Racquet (Penhold Racquet)** - It was the traditional China pen-hold fast attack style. Although he had the penhold grip technique, his backhand ability was weaker than the shake-hand grip. However, as a traditional China grip, it had its own uniqueness. ** 5. Combination rubber (rubber) selection ** 1. ** Beginner ** - It was suitable for reverse glue. Reversed rubber was the mainstream rubber in the world of table tennis. It had good ball control ability and was suitable for beginners to practice basic skills. If you choose rubber, the domestic 729 brand reverse rubber rubber is more suitable for beginners. The sponge can choose a slightly softer one, such as 38 - 42 degrees, which can maintain good ball control ability; if you want to choose a better one, you can choose the domestic Double Happiness brand Speedy Three Ordinary. ** 6. Choose from a brand perspective ** 1. ** Table tennis base plate ** - Local brands like Galaxy were cheaper, while foreign brands like Butterfly and Sticka were more expensive. In terms of performance, foreign brands were slightly better, but beginners might not be able to experience the difference, so beginners were recommended to choose the Galaxy brand. 2. ** Table tennis reverse-coated rubber ** - For beginners, the domestic 729 brand was more cost-effective. If they wanted a better one, they could consider the Double Happiness Speedy Three Normal Model. Foreign brands were not necessary for beginners because they were expensive and it was difficult for beginners to feel the difference.
