Question

The first blank for both questions is: "estimate of the standard ('distance' or 'score' or 'mean')"

Second blanks: "...between a ('sample mean' or 'sample mean difference' or 'score')"

Third Blanks: "...and the ('population mean difference' or 'population mean' or sample mean')"

The choices are the same for the corresponding blanks, first, second and third.

**Understanding the Estimated Standard Error in Independent-Measures t Statistics**

This section focuses on explaining the role of the estimated standard error in the denominator of the independent-measures t statistic.

**Key Concept:**
- The estimated standard error measures the standard discrepancy between a sample statistic and the population parameter it estimates.

**Detailed Explanation:**

1. **Function of the Independent-Measures t Statistic:**
- The denominator of the independent-measures t statistic provides an estimate of the standard error between a *sample mean difference* and the *population mean difference*.

2. **Condition when Null Hypothesis is True:**
- When the null hypothesis is true, the standard error is the standard deviation of the distribution of sample mean differences between a *sample mean* and a *population mean*.

This description assumes that the reader is familiar with basic statistical concepts, particularly hypothesis testing and statistical inference, and aims to clarify the importance and function of the standard error in t-tests.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
