There are 30 eggs altogether. Given that I have a varying number of data points for each surgeon (e.g. Is there a function that can tell if a number is equal or unequal, and if yes, how can I use it (what is the syntax)? Is there a function that can tell if a number is equal or unequal, and if yes, how can I use it (what is the syntax)? The reviewer in particular questioned whether I could trust my results that indicated statistical significance, given the very different sizes between the two groups. 2) Another study has two sample groups with almost exactly equal means (Group 1=5.67, Group 2=5.75), which to me intuitively says they are not statistically different, however again the data are not normally distributed (and not equal in size either Group 1=103, Group 2 = 221), so I am assuming I have to run a non-parametric test, which results in statistically significant differnece between the groups?? It would be fine–this isn’t uncommon. You're right that Welch is only available with one-way anova, at least in spss. Figure 3. The effect of marital status cannot be distinguished from the effect of age.”. However, i have a study in which i intend to KruskWallis and i would want to have my results in a table from.

Example:. So I’d suggest a consultation. One reviewer asked if I applied any “correction” to take into account the different sample size. Hello Sir, But I can tell you a group with n=1 (the highest depression) has no variance, so isn’t useful. Two of my independent variables have unequal sample sizes, for example: the first variable (depression) was drawn from a student sample, the depression variable has 6 ordinal levels with: n=55, 16, 6, 5, 4, 1 (in each level of depression). This means they work the same way. Would you agree with this concern? Or you’re saying you have 28 DVs? It’s common when both the IV and the DV have lopsided sample sizes.

So, I am wondering whether these results are reliable at all? The not equal sign can be typed as "\(\neq\)". You can put the weight in either GLM or Regression procedures. My problem is that even though an ANOVA shows significant differences for the three groups on a specific dependent variable, and the largest calculated mean-difference is between the smallest group and one of the other, post hoc tests cannot tell apart the smallest group from the group where the largest mean-difference appear. If the sum of marks scored by Mike and his sister is 25. M1a,b With small sample sizes, it’s almost never significant.

I made this activity to help my kiddos practice with identifying two number sentences as equal (so the equations are balanced) or unequal. After running a Mann-Whitney test, the results showed that none of the paired types were significantly different. The total number of participants is 24 (i.e., each of the 24 subjects did all the three conditions in the experiment). Both count the the frequencies of the combinations of these categories. total income, education between the two categories so as to say something about the effect of the road. Thank you! At best, it won’t answer the research question. At worst, it will answer it, but wrongly. These French digital task cards are a great activity for introducing fractions, identifying equal and unequal parts of a whole. I have two variables with unequal sample size. My question relates to planned contrasts in one way ANOVAs. In section 3.3, we introduce the Horvitz-Thompson estimator which can be used when the sampling is with or without replacement. I was running a Krustal-Wallis Test to determine any significance between each group. It is certainly reasonable to combine those groups, as long as it makes theoretical and logical sense.
