Compare activation rates between two consistently defined signup cohorts.
Description
Activation cohorts compare shares reaching a defined milestone.
Activation cohorts compare shares reaching a defined milestone.1
Compare activation rates between two consistently defined signup cohorts.
When to use Activation Cohort Comparison
Use this tool to compare activation rates between two consistently defined signup cohorts.
Prepare consistently defined customer counts, durations, costs or forecast assumptions. Keep aligned records and monetary amounts on a common period and currency basis.
How to use Activation Cohort Comparison and understand its results
- Prepare consistently defined customer counts, durations, costs or forecast assumptions. Keep aligned records and monetary amounts on a common period and currency basis.
- Enter firstCohortStarted, firstCohortActivated, secondCohortStarted, secondCohortActivated using the field table and calculation rules, then run the tool.
- Read firstActivationPercent, secondActivationPercent, changePoints. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| firstCohortStarted | First cohort started | number | Required |
| firstCohortActivated | First cohort activated | number | Required |
| secondCohortStarted | Second cohort started | number | Required |
| secondCohortActivated | Second cohort activated | number | Required |
Enter positive integer started counts and activated counts within each; return rates and signed percentage-point difference.
rate%=100activated/started; difference=second−first Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| firstActivationPercent | First activation percent | number |
| secondActivationPercent | Second activation percent | number |
| changePoints | Change points | number |
{
"input": {
"firstCohortStarted": 100,
"firstCohortActivated": 30,

"secondCohortActivated": 40
},
"output": {
"firstActivationPercent": 30,

}Limitations and assumptions
No cohort comparability, significance or causal attribution is assessed.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
