Data from the study of meditation and pain tolerance. Copy the data on paper and calculate everything you need to run the correct t-test including M's and SS. Then fill in your answers in the blanks provided. Higher scores indicate a more severe pain rating. Group 1 is BM. Group 2 is IM. Show your work step by step on paper.

4 7

2 6

Means for each group are (use 1 decimal place):

M1 = 2.8 M2 =5.6

Again using same data from the study of meditation and pain tolerance. Calculate the SS, pooled variance and SE from the raw data.

SS for each group are (use 1 decimal place): BM group SS1 = IM group SS2 =

pooled variance (whole number no decimals) =

standard error using 2 decimals (SEm1-m2) =

Again using same data from the study of meditation and pain tolerance. Calculate the t-value and decide if it is significant or not.

calculated t value (watch the sign and use 2 decimals) =

Is the difference between means in this study statistically significant? yes or no:

Again using t-value from the study of meditation and pain tolerance write a conclusion. The sentence should include all of the parts, most importantly 1) report significance, 2) include the stats, 3) describe the direction of the difference if it is significant and report the means.
