Question

This week you will collect time measurements and organize your observed data into a frequency distribution table and a relative frequency histogram. Start by choosing something you can time easily in seconds. (Thing about events that typically take between 20 seconds and 3 minutes.) You will need to collect at least 30 observations. Be as consistent as you can with your time measurements. Most of you have smart phones with easy-to-use apps with timers already built in. If your measurements are taken in minutes, you will need to convert the minutes to seconds by replacing each minute with 60 seconds. Round your measurements in seconds to two decimal places, which should be easy since that's pretty typical for stopwatches. Here are some ideas that you CAN use (even though I'd rather have you think of your own idea): How long it takes to drink 8 ounces of water How long it takes to walk 100 feet at a normal pace How long someone spends brushing their teeth Duration of a commercial (on TV or the radio) How long it takes to empty your bladder (Gross! But hey... science.) How long it takes you to make a shot from the free-throw line (or 3 point-line, if you're a baller) If you think of your own idea, I'll give you 2 points extra credit on this assignment. Feel free to check in with me if you're unsure that your own measurement idea is a good one! :) Once you collect all 30 measurements, organize your data into a frequency distribution with between 5 and 10 classes. I would like your distribution to have a column for each of the following: class limits, class boundaries, frequency, relative frequency, and cumulative frequency. After you've organized your data into a frequency distribution, it should be easy to make your graph by hand. Yes. By hand.* You will be making a relative frequency histogram of your collected data, so your horizontal axis will represent the class boundaries (the ones that overlap), and your vertical axis will represent the relative frequencies of each class (as either percents or decimals). Scale and label your axes clearly. Make sure your graph is neat and tidy. (I'm not going to dock points if you don't use a ruler, but keep it clean. If your work is typically messy, please do a rough draft graph first, then copy over all the essentials onto the version you will submit.) Attach a photo or scan of your graph to your post. You can choose to also photograph/scan your frequency distribution table, OR you can type that into your discussion post using the table feature in the rich text editing tools. The last thing you need to include in this assignment is description of the shape of your data. Here's a word bank to use in your description: skewed (right/left) symmetric bell-shaped uniform random U-shaped J-shaped reverse J-shaped bimodal multimodal You can lose points for not using descriptions that clearly apply, and you can lose points for using the wrong descriptive terms. You should know what each of those terms above mean. If you don't, please look it up or ask! In summary, your post needs to include: Your collected data, listed in ascending order A frequency distribution table A relative frequency histogram A sentence describing the shape of the distribution help?
