For "Atheist" groups, the median number of members is 107. For "Freethinker" groups, the median is 110. For "Humanist" groups, the median number of members falls at 55."Different" groups have a median number of members at 75.

Although the median numbers of members for "Atheist", "Freethinker", and "Other than Freethinker" groups fall slightly above the median for all groups, these group medians are still within the 95%CI range for all groups (48 to 115). "Humanist", "Different", and "Other than atheist" groups, though falling below the median for all groups, are still within the 95%CI range as well.

From the data available, there is insufficient evidence to suggest on the basis of membership that any particular label for groups is more effective than any other label.

"Atheist" groups cover a median of 1300 square miles per group with a 95% CI of 300 to 20,100square miles.

"Freethinker" groups cover a median of 2650 square miles per group with a 95% CI of 300 to 11,300 square miles.

"Different" groups cover a median of 1300 square miles per group with a 95% CI of 300 to 7900 square miles.

"Humanist" groups cover a median of 1300 square miles per group with a 95% CI of 300 to 7900 square miles.

No groups fall below a 300 square mile area within the 95% confidence range.

"Atheist" groups tend to have the broadest area of coverage, with highest median and upper limit of CI, followed closely by "Freethinker" groups. The medians for "Different" and "Humanist" groups are the same, however, "Humanist" groups have the lowest upper limit of CI of all groups at 2800 square miles. "Humanist" groups seem to generally have a more concentrated area of focus. More on this later in the report.

For all groups, the median for active members is about 23, with a 95%CI 15 to 30.

For "Atheist" groups 15, 95%CI 12 to 40 (n=9)

For "Freethinker" groups 25, 95%CI 9 to 30 (n=9)

For "Humanist" groups 25, 95%CI 15 to 60 (n=7)

For "Different" groups the median is 21, (n=4), and CI is the full range of data points.

While "Freethinker" and "Humanist" groups have higher medians than "Atheist" groups, the median for atheist groups still falls within the CI of the other two, though at the lower limit of the CI for "Humanist" groups. The upper limit of the CI for Atheist groups however is well within the range for both "Humanist" groups, and above the CI for "Freethinker". For this reason the data is insufficient to conclude that on the basis of active membership any group type is more effective than the others.

Ranking (excluding "Different") in descending order: "Humanist", "Freethinker" and "Atheist".

Regarding percentage of active members (n=29), the median is 25%, with a 95% CI of 17 to 33% of members actively participating.

For "Atheist" groups 17%, 95%CI 5 to 29% (n=9)

For "Freethinker" groups 30%, 95%CI 13 to 33% (n=9)

For "Humanist" groups 30%, 95%CI 6 to 75% (n=7)

For "Different" groups the median is 39.5% (n=4) and CI is the full range of data points.

While "Freethinker" and "Humanist" groups have higher medians than "Atheist" groups, the median for "Atheist" groups still falls within the CI of the other two, though near the lower limit of the CI for "Freethinker" groups. The upper limit of the CI for "Atheist" groups however is well within the range for both "Freethinker" and "Humanist" groups. For this reason the data is insufficient to conclude that on the basis of percentage of active membership any group type is more effective than are others.

Ranking Excluding "Different" in descending order: "Humanist", "Freethinker", and "Atheist".

The median of average distance traveled by members to attend group functions is 10 miles, with 95% CI of 10 to 15 miles (n=49).

For "Atheist" groups 10, 95%CI 5 to 30 (n=13)

For "Freethinker" groups 15, 95%CI 10 to 30 (n=13)

For "Humanist" groups 10, 95%CI 8 to 20 (n=14)

For "Different" groups the median is 10, 95%CI 10 to 20 (n=9).

Although the median for "Freethinker" groups is slightly higher than that of other groups, it is still within the CI’s of other groups, though at the upper limit of CI for All groups.

Also of note is that the upper limit of CI’s for "Humanist" and "Different" groups.

These points alone, however, do not indicate that one or more type groups elicit active members from farther away.

The median for group meetings for all groups is once per month (n=54), with 95%CI of 1 to 2 meetings per month.

For "Atheist" groups 1, 95%CI 1 to 4 (n=15)

For "Freethinker" groups 2, 95%CI 1 to 3 (n=15)

For "Humanist" groups 1, 95%CI 1 to 3 (n=14)

For "Different" groups the median is 1, 95%CI 1 to 3 (n=10).

For "Freethinker" groups, the median is higher, though the CI is comparable to other groups. For "Atheist" groups the upper limit of CI is higher, though the median is not.

While the CI is more likely to be affected by outliers (one or a few with values farther outside the ‘normal’ range), the median should not fluctuate as readily. The variable of "meetings per month" however, is trivial, and needs comparison with other variables to be of any use. More on this later in the report.

Although 52% of all groups do not charge membership fees (n=28), median fee amount for those who do (n=26) is $25/year, 95% CI $20 to $25/year.

For "Atheist" groups 66% do not charge a fee (n=12). 33% charge a fee (n=5).

Of atheist groups that charge a fee, the median fee is $24 per year, with a 95%CI of

$20 to $25 per year.

For "Freethinker" groups 66% do not charge a fee (n=12). 33% charge a fee (n=5).

Of atheist groups that charge a fee, the median fee is $24 per year, with a 95%CI of

$20 to $25 per year.

For "Humanist" 14% do not charge a fee (n=2). 86% charge a fee (n=12).

Of "Humanist" groups that charge a fee, the median fee is $25 per year, with a 95%CI of

$20 to $30 per year.

For "Different" groups 60% do not charge a fee (n=6). 40% charge a fee (n=4).

Of "Different" groups that charge a fee, the median fee is $30 per year

The greatest significance from the data discovered through this comparison, is that the majority of "Humanist" groups charge a membership fee. There may be a relationship between this (charging a fee), and lower overall membership.

Respondents were asked to rate their over-all satisfaction with their group (with 1 being completely miserable and 10 being ecstatic). The median response to this question was "8", with 95% CI of "8" being accurate itself (n=51).

For "Atheist" groups median 7.5, 95%CI 5 to 9 (n=14)

For "Freethinker" groups median 9, 95%CI 8 to 10 (n=15)

For "Humanist" groups median 8, 95%CI 7 to 8 (n=13)

For "Different" groups the median is 8, 95%CI 7 to 9 (n=9).

"Atheist" groups median ranks lowest. CI upper limit falls above "humanist" upper limit, at the upper margin of "Different" upper limit, and within that of "Freethinker"

"Freethinker" groups’ median ranks highest, with CI upper limit above all others, and Lower limit above "Humanist".

"Humanist" median is above "Atheist", below "Freethinker", and equal to "Different", with CI upper limit falling below lower limit of "Freethinker", and within the other two CI’s.

"Different" groups median rank above "Atheist", below "Freethinker", and equal to "Humanist" groups median, with CI upper limit passing above "Humanist" upper limit.

So….

Ranking in descending order of reported satisfaction: "Freethinker", "Different", "Humanist", and "Atheist".

Does this mean anything? Possibly…

Once again, more on this later in the report.

Respondents were asked to rate, according to the importance to their groups, four items on a 1-10 scale (where "1" was least important and "10" was most important). The items are "Local Activism", "National Activism", "Education", and "Social".

For "Local Activism", the median response for all groups was "7.5", with 95% CI between "5" and "8" (n=50).

For "Atheist" groups median 6.5, 95%CI 1 to 10 (n=14)

For "Freethinker" groups median 7, 95%CI 1 to 9 (n=14)

For "Humanist" groups median 7.5, 95%CI 4 to 8 (n=14)

For "Different" groups the median is 8, 95%CI 1 to 9 (n=8).

"Atheist" groups median falls lowest at 6.5, and "Different" groups falls highest at 8, followed by

Ranking in descending order of reported satisfaction: "Freethinker", "Different", "Humanist", and "Atheist".

For "National Activism", the median response for all groups was "3.5", with 95% CI between "2" and "5" (n=48).

For "Atheist" groups, the median 5.5, 95%CI 1 to 7 (n=14)

For "Freethinker" groups median 3, 95%CI 1 to 6 (n=14)

For "Humanist" groups median 3.5, 95%CI 1 to 8 (n=12)

For "Different" groups the median is 4.5, 95%CI 1 to 7 (n=8).

"Atheist" groups median falls highest at 5.5, and "Different" groups falls next highest at 4.5, followed by "Humanist" groups, and "Freethinker".

Of not, the "Humanist" groups though having median below "Atheist" and "Different" has the highest upper limit for CI, which makes ranking for this group in this section a bit more ambiguous. "Freethinker" groups, however rank lowest by median and CI.

For "Education", the median response was "8", with 95%CI matching that median at "8" as well (n=51).

For "Atheist" groups the median was 6, 95%CI 3 to 8 (n=14)

For "Freethinker" groups median 8, 95%CI 7 to 10 (n=14)

For "Humanist" groups median 8, 95%CI 8 to 10 (n=14)

For "Different" groups the median is 8, 95%CI 5 to 10 (n=9).

"Atheist" groups median falls lowest at 6, also with the lowest range for CI, with upper limit for CI falling at the lower end of CI for "Humanist" groups and near the lower limit of CI for "Freethinker" groups.

Ranking in descending order of importance of Education: "Humanist", "Freethinker", "Different", and "Atheist".

For "Social", the median response was 9, with 95%CI of between 8 and 10 (n=50).

For "Atheist" groups the median was 9, 95%CI 6 to 10 (n=14)

For "Freethinker" groups median 9.5, 95%CI 8 to 10 (n=14)

For "Humanist" groups median 8.5, 95%CI 6 to 10 (n=14)

For "Different" groups the median is 9.5, 95%CI 6 to 10 (n=9).

"Humanist" groups median falls lowest at 8.5, but with CI equal to all other groups save "Freethinker". "Freethinker", and "Different" groups have the highest medians at 9.5 with CI for "Freethinker" groups showing the highest lower limit at 8 to 10.
