In one sentence, describe what the following article is about: Sometimes, people who have difficulty staying balanced on escalators, or experience vertigo as they go down the escalator can have ear or eye issues. Get your eyes checked for any visual issues that may be causing imbalance or unsteadiness, and ask your doctor to check your ears for any issues that may be causing vertigo. Your doctor can diagnose your phobia based on your symptoms, as well as your medical, psychiatric, and social history. Be prepared to answer questions in a clinical interview about your fear of escalators and the severity of your fear.  The clinical definition of a phobia is a fear of an object or experience that is consistent for six months or more. You may experience panic attacks when exposed to the object or the experience, as well extreme distress or anxiety. You will likely recognize that your fear is irrational or unreasonable and be bothered that you cannot move past your phobia. Finally, your fear may so strong you will adjust your daily routine, your social life, or your work life to avoid confronting your phobia.  Once your doctor gives you an official diagnosis of escalaphobia, you can use this to get coverage for therapies and treatment for your issue. Your doctor can refer you to a certified psychologist, a cognitive behavior specialist, or even a hypnotherapist. Discuss these options, as well as the pros and cons of each option, before you agree to treatment.
Summary: Get your ears and eyes checked. Ask for an official diagnosis. Get a referral for a therapist.

In one sentence, describe what the following article is about: Each and every word and symbol in a statistics problem is important, and there can be a lot of information you need to absorb. To get all the information you need, read the problem slowly, and multiple times. If necessary, annotate the problem. Note what each part of the equation represents and what you're solving for.  For example, the equation for standard deviation is variance{\displaystyle {\sqrt {variance}}}. Next to that formula, you might want to write the formula for the variance: ∑(X-µ2/N After you've written out the variance formula, note what each component means. ∑ means "sum," the (X-µ) represents the different between each term in the set and mean, and that N is the total number of points in the data set. When you get to parts of the text that explain a concept or formula, work them out yourself alongside the book, even if the book gives you the answer. Working through the problems as you study can help you really solidify the concepts you’re learning before you get to problems you’re expected to solve on your own. Even if you have no idea where to start, get your pencil moving and try to get through what you can. That way, if you need to ask for additional help, you can show your professor or tutor what you’ve already done. Your instructor will likely set you homework that includes a few problems for each statistical concept you studied that week. If you find that 1 particular concept is hard for you, work out 2 or 3 extra problems on that concept. Being good at statistics requires actually doing the problems, so extra practice will always help. If you're not sure which extra problems you should do, ask your instructor. They can give you additional work from your textbook or workbook, or direct you to where you might find extra problems. It's easier to learn statistical concepts – what each formula means and what it can help you figure out – rather than long, complicated formulas. Focus on learning the concepts behind the formulas – you can always look up the formulas later.
Summary:
Read each problem carefully. Use pencil and paper while you study. Work out extra problems. Focus on concepts, not formulas.
