For each STAT CALC menu item, if neither Xlistname nor Ylistname is specified, then the default list names are L1 and L2. If you do not specify freqlist, then the default is 1 occurrence of each list element.
Frequency of Occurrence for Data Points For most STAT CALC menu items, you can specify a list of data occurrences, or frequencies (freqlist). Each element in freqlist indicates how many times the corresponding data point or data pair occurs in the data set you are analyzing. For example, if L1={15,12,9,14} and FREQ={1,4,1,3}, then the TI-83 Plus interprets the instruction 1.Var Stats L1, FREQ to mean that 15 occurs once, 12 occurs four times, 9 occurs once, and 14 occurs three times. Each element in freqlist must be 0, and at least one element must be > 0. Noninteger freqlist elements are valid. This is useful when entering frequencies expressed as percentages or parts that add up to 1. However, if freqlist contains noninteger frequencies, Sx and Sy are undefined; values are not displayed for Sx and Sy in the statistical results. 1.Var Stats

Press and [H] [G] [H] [T] at the List: prompt (alpha-lock is on). Press 99 to enter a 99 percent confidence level at the C.Level: prompt. 6. Press to move the cursor onto Calculate, and then press. The confidence interval is calculated, and the TInterval results are displayed on the home screen.
Interpret the results. The first line, (159.74,173.94), shows that the 99 percent confidence interval for the population mean is between about 159.74 centimeters and 173.94 centimeters. This is about a 14.2 centimeters spread. The.99 confidence level indicates that in a very large number of samples, we expect 99 percent of the intervals calculated to contain the population mean. The actual mean of the population sampled is 165.1 centimeters, which is in the calculated interval. The second line gives the mean height of the sample used to compute this interval. The third line gives the sample standard deviation Sx. The bottom line gives the sample size n. To obtain a more precise bound on the population mean m of womens heights, increase the sample size to 90. Use a sample mean of 163.8 and sample standard deviation Sx of 7.1 calculated from the larger random sample. This time, use the Stats (summary statistics) input option. 7.

The regression equation is automatically stored to RegEQ (VARS Statistics EQ secondary menu). If you enter a Y= variable name at the RegEQ: prompt, the calculated regression equation is automatically stored to the specified Y= equation. In the example below, the regression equation is stored to Y1, which is then selected (turned on). In the example:
L3={ L4={ 59 6474} 70 7284}
When LinRegTTest is executed, the list of residuals is created and stored to the list name RESID automatically. RESID is placed on the LIST NAMES menu.
Note: For the regression equation, you can use the fix-decimal mode setting to control the number of digits stored after the decimal point (Chapter 1). However, limiting the number of digits to a small number could affect the accuracy of the fit.

ANOVA(

ANOVA( (one-way analysis of variance; item F) computes a one-way
analysis of variance for comparing the means of two to 20 populations. The ANOVA procedure for comparing these means involves analysis of the variation in the sample data. The null hypothesis H0: m1=m2=.=m k is tested against the alternative Ha: not all m1.mk are equal.

TI-83 Plus Communication Link 646
Note: You can transfer all real variables, pics, and programs from a TI-82 to a TI-83 Plus if they fit in the RAM of the TI-83 Plus. The RAM of the TI-83 Plus is slightly less than the RAM of the TI-82.
Receiving from a TI-82 Unresolved Differences The software built into the TI-83 Plus cannot resolve some differences between the TI-82 and TI-83 Plus. These differences are described below. You must edit the transmitted data on the receiving TI-83 Plus to account for these differences. If you do not edit these differences, the TI-83 Plus will misinterpret the data. The TI-83 Plus reinterprets TI-82 prefix functions to include open parentheses, which may add extraneous parentheses to transmitted expressions. For example, if you transmit sin X+5 from a TI-82 to a TI-83 Plus, the TI-83 Plus reinterprets it as sin(X+5. Without a closing parenthesis after X, the TI-83 Plus interprets this as sin(X+5), not the sum of 5 and sin(X). If a TI-82 transmits an instruction that the TI-83 Plus cannot translate, the ERR:INVALID menu displays when the TI-83 Plus attempts to execute the instruction.
For example, on the TI-82, the character group Un-1 is pasted to the cursor location when you press y [UnN1]. The TI-83 Plus cannot directly translate Un-1 to the TI-83 Plus syntax u(nN1), so the ERR:INVALID menu is displayed.
Note: TI-83 Plus implied multiplication rules differ from those of the TI-82. For example, the TI-83 Plus evaluates 12X as (12)X, while the TI-82 evaluates 12X as 1(2X) (Chapter 2).
Receiving from a TI-73 The TI-83 Plus can receive real numbers, pics, real lists L1 through L6, and named lists from a TI-73. Categorical lists (lists containing alpha characters as list elements) cannot be sent from a TI-73 to a TI-83 Plus. To transmit data to a TI-83 Plus from a TI-73: 1. Set the TI-83 Plus to receive. 2. Press on the sending TI-73 to display the APPLICATIONS menu. 3. Press on the sending TI-73 to select 1:Link and display the LINK SEND menu. 4. Choose 0:Vars to TI83. and then select the items you want to send.
