Question

Of the high-education group, the average number of three-plus-syllable words is 23.611123.6111 with a standard deviation of 11.072711.0727. Of the medium-education group, the average number of three-plus-syllable words is 15.222215.2222 with a standard deviation of 8.83558.8355. Of the low-education group, the average number of three-plus-syllable words is 10.510.5 with a standard deviation of 2.25572.2557. There are eighteen magazines sampled in each group.

Complete the following ANOVA summary table (α=0.10α=0.10). Round your answers to three decimal places, if necessary, and round any interim calculations to four decimal places.

The table presented is a typical ANOVA (Analysis of Variance) summary table, used in statistical analyses to test for significant differences between group means. Here is the transcription of the table: | Source | SS | df | MS | F | P-value | |----------|-----|----|-----|----|---------| | Between | | | | | | | Within | | | | | | | Total | | | | | | **Explanation of the Columns:** - **Source:** This column identifies the variation sources: "Between" represents the variation between groups, "Within" denotes the variation within each group, and "Total" is the combined variation of both sources. - **SS (Sum of Squares):** This is the measure of variance. SS for "Between" shows the variation due to differences between group means, while SS for "Within" represents variation within each group. "Total" SS is the sum of both. - **df (Degrees of Freedom):** A statistical property that accounts for the number of values in the calculation that are free to vary. "Between" and "Within" each have their respective degrees of freedom, and the "Total" is the sum of both. - **MS (Mean Square):** This is the average variance (SS divided by df). MS "Between" indicates average variance between groups, and MS "Within" shows average variance within the groups. - **F:** This is the F-statistic, a ratio of variances that determines if the variance between group means is significantly greater than within-group variance. - **P-value:** This is the probability value that helps to determine the significance of the results. A lower P-value typically indicates a significant difference between groups. This table layout, when filled with data, helps determine if there are statistically significant differences among group means in a study.
