Platelets (thrombocytes) are colorless blood cells that help blood clot. SRS 3. independent samples 4. normal distribution or n is large (>30) One Sample T-Test (for mean) 1. is unknown 2. In a nutshell, the Central Limit Theorem says you can use the normal distribution to describe the behavior of a sample mean even if the individual values that make up the sample mean are not normal themselves. By Deborah J. Rumsey, David Unger . Blood test. The criteria can be in the form of a number, expression, cell reference, or text that define which cells shall be counted. The 10% condition ensures that we can use the formula for standard deviation. In adults, normal platelet count is 150,000 to 450,000 platelets per microliter of blood. You can find a few more ways to count cells with OR logic in this tutorial: Excel COUNTIF and COUNTIFS with OR conditions. This is the currently selected item.

Unlike the older COUNTIF function, COUNTIFS can apply more more than one condition at the same time.Conditions are supplied with range/criteria pairs, and only the first pair is required. Criteria_range1 (required argument) This is the first range that would be evaluated with the associated criteria. Criteria1 (required argument) The conditions to be tested against the values. The Count function counts the number of records that contain a number in a single-column table.The CountA function counts the number of records that aren't blank in a single-column table. x][s~w_jT7HK)R{{K#{j%23r6 9 Seh4 f_eV|}"+r[*S_F\_y 5e&cSy?y;6~52Y6v:"hC When performing a count, MongoDB can return the count using only the index if: the query can use an index, the query only contains conditions on the keys of the index, and; the query predicates access a single contiguous range of index keys.
