Applications for ti plus graphing calculator 55 pages. It will not explain the underlying statistics but instead focus on how best to use the TI, TI Plus, and TI Plus calculators in computing them. After the data instrumennts collected it needs to be organized and interpreted. There is a limit to how much of the work can be done effectively without the help of some texas instruments ti 83 plus manual download of technology.
The TI was first released inimproving upon its predecessors the TI and TI with the addition of many advanced statistical and financial functions. Texas instruments ti 83 plus manual download input data or to make changes to an existing set of data values use the Edit function.
Press the number 1 key. If your stat list editor does not show the columns labeled L1, L2, and L3 you can set up the Editor by selecting SetUpEditor on the previous screen. Page 7 Use the up and down arrow keys to go back and forth between the numbers. Try changing the value of one of the entries by typing in a new weight. Clearing a List of Data Values After a list of data values is no longer needed you can delete the values by using one of the following methods.
To see this, go into the Just follow the instructions on the screen. Page 10 Exercises 1. Store the following numbers into the list L2: 11, 23, 35, 47, 59 2. Store the following numbers into the list ABC: inshruments, 3, 5, 7, 11, 13 3. Page Organizing Data One of the simplest ways of organizing texas instruments ti 83 plus manual download is to group together similar values.
Use the arrow keys to move from one bar to the other. The histogram provides us with the following information. The data ranges from The steps to create the dotplot are very similar to those needed to create the histogram. We will use the data stored under the label WORK that we used to create the histogram in the previous example. Press the STAT key. Page 16 Exercises 1. Take the following statistics exam scores and construct a frequency histogram for them with classes from 50 to 59, from 60 to 69, from 70 to 79, from 80 to 89, нажмите чтобы перейти from 90 to Create a dot plot using the above data values.
Solutions 1. Page Numerical Descriptive Measures After learning about percentiles, another visual display can be created called the box-and-whisker ppus. There are two ways of using this command: with ungrouped data and with grouped data. Page 18 Downloae Prices of CDs. The following data values are the prices of the same popular CD sold from ten different discount stores. Enter the data values into L1. Page 19 The last five numbers minimum, first quartile, по этому адресу, third quartile, and ddownload are collectively known as посмотреть больше five-number summary of the data.
From the five-number-summary we can compute the range, which is the difference between maxX and minX, and the interquartile range, which texas instruments ti 83 plus manual download the difference between Q3 and Q1.
Use the down arrow key to see that the median payroll is 75 million dollars. Page 21 Grouped Data Sometimes a set of data values has many numbers that show up over and over again. Instead of typing those numbers in over and over again you can save time by typing in the numbers that repeat along with how many times it repeats.
Example: Multiple Frequencies The following is a list of data values that are ungrouped. Once the data is sorted, the kth percentile is found by counting up to the kth position in the sorted data and dividing by the number of data values in the data set.
Since there are a number of different types of plots available on the calculator, it is important to make sure that all other plots are turned off before you begin or you graph will be cluttered with several unrelated plots being graphed at the same time. Page 25 Set the Freq: to 1. Press the ZOOM key. Press the number 9 key. We have two different types of box-and-whisker plots to select from. One will separate outliers from the maximum or minimum value and the other will include the outliers in to whiskers.
Pluw you select the picture that shows two dots after the maximum on the plot, the outliers will be shown outside of the whiskers. Page 26 Exercises 1. Find the mean and sample standard deviation for the following data: 34 23 55 91 23 34 12 34 98 23 2. Find the median and interquartile range for the following grouped data: Score Frequency 3. What is the percentile rank of 82 in the following data? Computer simulations are a common example of the need for random occurrences within a structured setting.
These numbers are called pseudo-random numbers since they are not totally random. Generating Random Numbers Between any Two Values If you would like to generate random real numbers that are equally likely dowmload occur and fall within a specified range of values manuzl can use the rand function with some additional commands.
There are many situations in statistics where you need to generate numbers from distributions where the numbers are not equally likely to downlload.
Two of the most commonly used distributions used in statistics are the normal and the binomial. Page 30 The syntax for texas instruments ti 83 plus manual download functions are similar to those needed for the texas instruments ti 83 plus manual download function. Page 31 Exercises 1. Create a random integer value between 50 and 60 inclusive. Create a random real number between 3 and Generate 15 random integer values between 1 and 50 and store them in L1.
Select 10 values from a normally distributed population with a mean of 22 and a standard deviation or 2. Enter the x values into L1. Enter the P x probabilities into L2. After you press the ENTER key you downlpad get the descriptive statistics which includes the population mean and standard deviation.
Page 34 Permutations Another common function needed to compute dependent probabilities that uses factorial is the permutation formula. The number of permutations is normally written as nPr; on the calculator with the symbol P written between n and r, where n is the total number of elements, and texss is the number being selected. Page 35 Binomial Probabilities The command for computing binomial probabilities is binompdfwhich is located on the DISTR page which is found in yellow above the fourth key in the fourth row.
To find the probability of x successes out of n trials, each with probability p of success, type binompdf n, p, texas instruments ti 83 plus manual download. Page 36 Find the probability that at most 2 or less of these 10 packages will not arrive at its destination within the specified time. Page 38 Exercises 1. Find 13! Find the number of ways to deal a five-card hand from a deck of 52 cards. A company has etxas fork-lifts.
Page Continuous Random Variables Traditionally normal distribution probabilities were figured using a normal distribution table. Texas instruments ti 83 plus manual download calculator reduces the texas instruments ti 83 plus manual download needed to perform the calculations and reduces the rounding errors that occur because of the brevity of the tables in elementary statistics textbooks.
Type in 1, 0, 1 to get normalpdf 1,0,1. To find the probability of getting a value that falls within a range of values from the standard normal distribution you can use the normalcdf function which stands for normal cumulative density function. Page 41 Press the number 2 key.
Type in the number Press the 2 key and then thecomma key to get the exponential sign E. Type in 99, 0, 1 after the E. The probability is. Example: Finding the Area to the Right To find the area to the right of a number a, type normalcdf a, 1E Page 42 Example: Finding the Area Between two values. To find the area between two numbers a and b, type normalcdf a, b, 0, 1.
Find the probability of getting a value between 1. Page 43 Find the probability of getting a score less than 32 given the distribution is normally distributed with a mean of 45 and a texxas deviation of Using the normalcdf function and typing in -1E99, then the score 32 with a mean of 45 and standard deviation of 12 we get the probability.
Press dosnload number 3 key. Type in. Page 45 Exercises 1. What is the probability that a z-score will lie between 2 and 3?
