| - | **Mean **- The average of a set of numbers. This measure can be combined across populations if there are two means reported. This is NOT the same thing as Least Square (LS) mean. | + | | <font 11pt/ |
| - | + | | <font 11pt/ | |
| - | **Median** - The middle value of a listed set of numbers. This measure can not be combined or used as a mean. | + | | <font 11pt/ |
| - | + | | <font 11pt/ | |
| - | **Standard Deviation (SD)** - A measure of the amount of variance within a set of numbers. Typically reported with a mean value using the symbol '**±'** | + | | <font 11pt/ |
| - | + | | <font 11pt/ | |
| - | **Standard Error (SE)** - The standard deviation of a sample of the larger population. This is NOT the same thing as SD and should not be used in replacement of SD. | + | |
| - | + | ||
| - | **Range** - The difference between the highest and lowest numbers in a given set. Typically given alongside the median. | + | |
| - | + | ||
| - | **Interquartile Range (IQR)** - The difference between the upper and lower quartiles. This is NOT the same thing as Range and should not be used as a replacement. | + | |

| * Look at the sunburst diagram in qualitative synthesis and evaluate gap teeth. Gap teeth occur when a study has been tagged at the higher level instead of the lower, most specific level. If studies are tagged with Study Design instead of the most specific tag, this may result in gap teeth. Gap teeth can also result when there is a small amount of studies tagged. | * Look at the sunburst diagram in qualitative synthesis and evaluate gap teeth.
