Excel Box and Whisker Diagrams (Box Plots) Box and Whisker Charts (Box Plots) are commonly used in the display of statistical analyses. Microsoft Excel does not have a built in Box and Whisker chart type, but you can create your own custom Box and Whisker charts, using stacked bar or column charts and error bars.
This tutorial shows how to make box plots, in vertical or horizontal orientations, in all modern versions of Excel. In its simplest form, the box and whisker diagram has a box showing the range from first to third quartiles, and the median divides this large box, the “interquartile range”, into two boxes, for the second and third quartiles. The whiskers span the first quartile, from the second quartile box down to the minimum, and the fourth quartile, from the third quartile box up to the maximum. Sample Data and Calculations To play along at home in Excel 2007 or 2010, download the workbook Excel_2007_Box_Plot_Workbook.xlsx. Let’s use the following simple data set for our tutorial. All of these values are positive. How to Read and Use a Box-and-Whisker Plot. The box-and-whisker plot is an exploratory graphic, created by John W.
Tukey, used to show the distribution of a dataset (at a glance). Think of the type of data you might use a histogram with, and the box-and-whisker (or box plot, for short) could probably be useful. The box plot, although very useful, seems to get lost in areas outside of Statistics, but I’m not sure why. It could be that people don’t know about it or maybe are clueless on how to interpret it. Reading a Box-and-Whisker Plot Let’s say we ask 2,852 people (and they miraculously all respond) how many hamburgers they’ve consumed in the past week.
Take the top 50% of the group (1,426) who ate more hamburgers; they are represented by everything above the median (the white line). Find Skews in the Data The box-and-whisker of course shows you more than just four split groups. Want to learn more about making data graphics? KS2 Bitesize Maths - Mode, median, mean, range : Read. Standard Deviation and Variance. Deviation just means how far from the normal Standard Deviation The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is easy: it is the square root of the Variance. Variance The Variance is defined as: The average of the squared differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers)Then for each number: subtract the Mean and square the result (the squared difference).Then work out the average of those squared differences.
Example You and your friends have just measured the heights of your dogs (in millimeters): The heights (at the shoulders) are: 600mm, 470mm, 170mm, 430mm and 300mm. Find out the Mean, the Variance, and the Standard Deviation. Your first step is to find the Mean: Answer: Mean = 600 + 470 + 170 + 430 + 3005 = 19705 = 394 so the mean (average) height is 394 mm. Now we calculate each dog's difference from the Mean: So the Variance is 21,704 Formulas.
7.1.6. What are outliers in the data? The data set of N = 90 ordered observations as shown below is examined for outliers: The computations are as follows: Median = (n+1)/2 largest data point = the average of the 45th and 46th ordered points = (559 + 560)/2 = 559.5 Lower quartile = .25(N+1)th ordered point = 22.75th ordered point = 411 + .75(436-411) = 429.75 Upper quartile = .75(N+1)th ordered point = 68.25th ordered point = 739 +.25(752-739) = 742.25 Interquartile range = 742.25 - 429.75 = 312.5 Lower inner fence = 429.75 - 1.5 (312.5) = -39.0 Upper inner fence = 742.25 + 1.5 (312.5) = 1211.0 Lower outer fence = 429.75 - 3.0 (312.5) = -507.75 Upper outer fence = 742.25 + 3.0 (312.5) = 1679.75 From an examination of the fence points and the data, one point (1441) exceeds the upper inner fence and stands out as a mild outlier; there are no extreme outliers. Catch the ruler!
Who has the quickest reaction time? Find out with this experiment. What you need: A ruler Pen Paper Friends or family How to find out who has the quickest reaction time: Hold the ruler at head level with your arm stretched out. This table lets you convert distance on the ruler to reaction time. Who had the fastest reactions? The person who catches the ruler at the lowest measurement. Why? The faster you react and grab the ruler, the less time the ruler will be falling. Our eyes see the ruler being dropped. The brain then sends signals to the muscles in the arm and hand to tell them to catch the ruler. These signals travel very quickly. Extras Repeat the experiment and try it out on lots of people. Email Planet Science and let us know your fastest reaction time! Ruler Dropping Experiment. Ruler Drop Test: GENDER AFFECT REACTION TIME.
2. Ruler drop test : Reaction Time. Reaction Time | The Wonders of Physics | University of Wisconsin–Madison. 1. Have your friend hold a yardstick from the top so that it is up and down with the bottom several feet above the floor. Your friend may have to stand on a chair to do this. 2. You hold your fingers opposite the 18-inch mark, but don't touch the stick! Without warning your friend should let go of the yardstick, and you should try to catch it with your fingers. 3. Notice what inch mark your fingers are on when you catch the stick. Why do you think it takes time for your fingers to react when your eyes see the stick start to fall?
What’s going on? Measure Reaction Time Science Experiment. For Olympic runners and swimmers, a fraction of a second is often the difference between winning a gold medal or a bronze. Indeed, it's the distance between winning any medal or returning home with nothing but hopes at another chance in four more years. And while its impact is most dramatic in running events, speed isn't only a matter of crossing the finish line first. In sports, reaction time, the interval between stimulation and reaction, often determines who wins and who loses. Even more importantly, in real-life situations, like when driving a car, it can mean the difference between life and death. Measure your reaction time with the following project. What You Need: Meter stick Dollar bill (optional) Flat, sturdy surface, like a tabletop or desktop One or more partners Reaction time table PDF What You Do: Have your partner sit or stand with their arm on the flat surface so their wrist extends beyond the edge.
What Happened: For further study: File:REACTION.DOC. File: REACTION.DOC Background It takes every person a little time to react to any event. For example, there is a small delay before you apply your brakes after you see the stop lights of a car just in front of you go on. This time is called your reaction time.
This experiment will permit you to measure your reaction time and to compare your time with that of other people in your class. The simplest way to measure a short time is to use the stop watch which came with your kit of parts. An indirect measurement is one in which a quantity other than the one desired is measured. To understand the principle involved, you might want to review the parts of your text which discusses falling bodies. Where y is the distance dropped, g is the acceleration due to gravity (9.8 m/s2) and t is the time of fall.
Which was obtained by solving (1) for t. References 1. 2. 3. 4. 5. 6. Materials Another person A ruler (longer than 25 cm) Instructions to be a member of this class. Extensions Report. Experiment: How Fast Your Brain Reacts To Stimuli. The knee reflex arc is a spinal reflex, and the circuit is drawn above. This picture shows how the sensory (afferent) neuron sends information through the dorsal root ganglion into the spinal cord; where the signal splits into two different paths. The first is the motor neuron (efferent) leading back to the quadriceps. When your quad muscle's motor neuron receives the information it fires and causes your lower leg to spring forward up in the air. The second signal from the sensory neuron travels to an interneuron which sends a signal to the motor neuron (efferent) leading to the hamstring. You may be asking how a knee reflex arc and a soccer player dealing with an oncoming ball are different.
When a soccer player realizes the ball is blistering towards him, there is visual information that has to be processed and decisions regarding a correct course of action. Like all science, the history of the reaction time discovery is peculiar. Procedure Here is the table for the first experiment: Ruler Drop Test. Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we need to bear in mind the factors that may influence the results. Objective The objective of this test is to monitor the athlete's reaction time.
Required Resources To conduct this test, you will require: Metre ruler Assistant How to conduct the test The ruler is held by the assistant between the outstretched index finger and thumb of the athlete's dominant hand so that the top of the athlete's thumb is level with the zero-centimetre line on the ruler The assistant instructs the athlete to catch the ruler as soon as possible after it has been released The assistant releases the ruler and the athlete catches the ruler between their index finger and thumb as quickly as possible The assistant is to record the distance between the bottom of the ruler and the top of the athlete's thumb where the ruler has been caught.

Reaction Times and Sprint False Starts. Beating the Gun or Running Fast Athletics sprint events begin with a sequence of events: Gun goes off Sound travels from gun to ear ear registers sound, sends impulse to brain brain processes sound, sends signal to start running. signal is received by muscles; sprinter goes Except for step 1, these events are loosely described as the athlete's reaction time. Major meets conducted by the IAAF record reaction times, and usually publish them on their web-site. When athletics sprint events separate athletes and world records by hundredths of a second, its worth appreciating the magnitude of the start events and particularly to consider their impact on timing accuracy. Reaction Time The reaction time is the time is takes for the runner to respond to the start signal and begin leaving the starting blocks. Propagation Delays Someone standing on the finish line, 100m away, won't hear the gun until 0.303 seconds after the start.
An athlete in Lane 8 is about 8.5 m from one in Lane 1. Conclusion. How Fast Is Your Reaction Time? Please ensure you have JavaScript enabled in your browser.
