Problem: Article: Most wild-caught females have already mated and are capable of laying eggs. If you catch one, you could coax her to lay eggs. For butterflies, set them up in a cage with a water bottle and host clippings next to the light source (preferably sunlight). This will encourage her to oviposit. You may also want to keep her in a dark, cool area for a couple of days to help her acclimate to her new surroundings. Moths are much easier than butterflies. If you catch an adult female moth, you can simply place her in a large paper bag, fold it up, and leave her there for a couple of days. She'll likely deposit eggs on the inside of the bag. Tear the bag, removing the eggs without touching them, and place them into a more suitable container. Since monarch butterflies are so popular, there are Monarch farms where you can order monarch caterpillars, like from Monarch Watch. They can ship the little critters to you unharmed. The only drawback to this is that you still have to find their food, the Milkweed. If it's not in your area, you'll have to order or grow it to successfully raise the Monarch. If you cannot find caterpillars in your yard or it's just the wrong time of year (it varies by locale), there are "caterpillar suppliers" for just this reason. Most companies have a wide variety of species to choose from and you know just what you'll end up with. Painted Ladies are probably the easiest, as you can just buy growth medium for them to feast on. However, this is a little less exciting then finding then on your own and knowing what they really like to eat. If you can, spend some time scoping out your garden. Exhaust all possibilities before you turn to the caterpillar farm.
Summary: Consider catching an adult female. Visit a monarch farm. Buy caterpillars from a supplier.

Problem: Article: The standard deviation is a measure of how spread out your data is. It gives you information on how similar each data point is within your sample, which helps you determine if the data is significant. At first glance, the equation may seem a bit complicated, but these steps will walk you through the process of the calculation. The formula is s = ((xi )2/(N 1)). s is the standard deviation. indicates that you will sum all of the sample values collected. xi represents each individual value from your data. is the average (or mean) of your data for each group. N is the total sample number. To calculate the standard deviation, first you must take the average of the samples in the individual groups. The average is designated with the Greek letter mu or . To do this, simply add each sample together and then divide by the total number of samples. For example, to find the average grade of the group that read the material before class, let's look at some data. For simplicity, we will use a dataset of 5 points: 90, 91, 85, 83, and 94. Add all the samples together: 90 + 91 + 85 + 83 + 94 = 443. Divide the sum by the sample number, N = 5: 443/5 = 88.6. The average grade for this group is 88.6. The next part of the calculation involves the (xi ) portion of the equation. You will subtract each sample from the average just calculated. For our example you will end up with five subtractions. (90 88.6), (91- 88.6), (85 88.6), (83 88.6), and (94 88.6). The calculated numbers are now 1.4, 2.4, -3.6, -5.6, and 5.4. Each of the new numbers you have just calculated will now be squared. This step will also take care of any negative signs. If you have a negative sign after this step or at the end of your calculation, you may have forgotten this step. In our example, we are now working with 1.96, 5.76, 12.96, 31.36, and 29.16. Summing these squares together yields: 1.96 + 5.76 + 12.96 + 31.36 + 29.16 = 81.2. The formula divides by N 1 because it is correcting for the fact that you haven't counted an entire population; you are taking a sample of the population of all students to make an estimation. Subtract: N 1 = 5 1 = 4 Divide: 81.2/4 = 20.3 Once you have divided by the sample number minus one, take the square root of this final number. This is the last step in calculating the standard deviation. There are statistical programs that will do this calculation for you after inputting the raw data. For our example, the standard deviation of the final grades of students who read before class is: s =20.3 = 4.51.
Summary: Define the formula for standard deviation. Average the samples in each group. Subtract each sample from the average. Square each of these numbers and add them together. Divide by the total sample number minus 1. Take the square root.

Problem: Article: Card counters are notorious for playing blackjack for hours and hours, often without eating or enjoying the amenities available at the resort. Acting like a tourist just looking for a simple good time may take the suspicion off of you. You want to blend in. Busting out your three-piece Armani suit is not what you want to do when starting your card counting career at your local casino. Leave the Italian suede at home and act like a regular Joe. Dealers are trained to shuffle the deck upon an unexplainable increase in the bet. For this reason, only up your bet in small increments and at seemingly random points in the game. This may seem counter to making money, but if you get thrown out, you'll be making zero. No, card counting isn't illegal, but it is heavily frowned upon and you can be asked to never return. This is why we had you practicing with the TV, radio, and several messy, loud-mouthed children. If you are so busy counting your lips are practically moving, it's a dead giveaway. Go ahead, get a drink, make small talk. Enjoy yourself. Counters have a reputation for being "zoned in" to the game. He will remain fixated on their cards while everyone else is looking at a gorgeous woman. Don't be that guy. You need to be proficient enough at counting that you can carry on a conversation. Chat with the dealer about how their day is going. If the pit boss comes up, chat with him, too. Many dealers know how to count cards. A dealer that likes you will be more likely to wait before shuffling on a favorable deck and shuffle sooner on a bad one. A dealer can help you or hurt you. Motivate the dealer to be for you. Same goes for the entire pit crew -- get them on your side, your not-so-heinous crime may slide under their radar. At any time, there are hundreds of cameras going on in the casino in addition to the eyes of the dealers, those in the pit (behind the tables), and the security staff. If they'll catch a waitress for serving a customer every 18.37 minutes, they'll definitely have the attention span to monitor you. Because of this, it's very important to be on your best behavior. If a casino suspects you're counting, they probably won't come right out and say it. They may have someone start a conversation with you to distract you, assign you a high-speed dealer, shuffle spontaneously or change the betting rules. If any of these happen, back down slowly, but immediately. When you hit a table, stay there for a spell. Why would you leave? And when you make your moves at this table, take a second to think about it. Normal blackjack players haven't spent the past three months staring at this exact set up in black and white. Everything you do needs to be nonchalant and casual. Do not jump from table to table every time the deck sours. This will bring you to the attention of the casino personnel fast. Make minimum bets until the deck is richer. Increase casually because you're doing well -- not because you know what's about to come.
Summary:
Act like a tourist. Let your bet ride, if you need to increase the bet. Appear to be interested in other things besides the game. Tip the dealer. Know who's watching you. Do everything slow.
