What is the formula for a two sample t-test?

The test statistic for a two-sample independent t-test is calculated by taking the difference in the two sample means and dividing by either the pooled or unpooled estimated standard error. The estimated standard error is an aggregate measure of the amount of variation in both groups.

What is the T in the T test?

The t-value measures the size of the difference relative to the variation in your sample data. Put another way, T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.

Is a ti 84 allowed on the SAT?

The ACT is somewhat stricter than the SAT, prohibiting calculators with CAS (“computer algebra system”) functionality, whereas these are generally allowed on the SAT. Most popular high school calculators, like the Texas TI-83 and TI-84, are permitted.

What kind of batteries do TI-84 calculators use?

The TI-83 and TI-84 use a CR1616 or CR1620 battery, which you can order through Calcblog’s Amazon.com account to support our site. The TI-89 uses a different battery, the SR44SW. Be sure to refer to your calculator’s manual for the proper backup battery to use, which may be different than what we have listed here.
