# RunnerResult
<Class id="qiskit.providers.ibmq.RunnerResult" isDedicatedPage={true} github="https://github.com/qiskit/qiskit-ibmq-provider/tree/stable/0.17/qiskit/providers/ibmq/runner_result.py" signature="RunnerResult(backend_name, backend_version, qobj_id, job_id, success, results, date=None, status=None, header=None, **kwargs)" modifiers="class">
Bases: `qiskit.result.result.Result`, `qiskit.providers.ibmq.runtime.program.result_decoder.ResultDecoder`
Result class for Qiskit Runtime program circuit-runner.
## Methods
<span id="qiskit-providers-ibmq-runnerresult-data" />
### data
<Function id="qiskit.providers.ibmq.RunnerResult.data" signature="RunnerResult.data(experiment=None)">
Get the raw data for an experiment.
Note this data will be a single classical and quantum register and in a format required by the results schema. We recommend that most users use the get\_xxx method, and the data will be post-processed for the data type.
**Parameters**
**experiment** (*str or* [*QuantumCircuit*](qiskit.circuit.QuantumCircuit "qiskit.circuit.QuantumCircuit") *or*[*Schedule*](qiskit.pulse.Schedule "qiskit.pulse.Schedule") *or int or None*) the index of the experiment. Several types are accepted for convenience:: \* str: the name of the experiment. \* QuantumCircuit: the name of the circuit instance will be used. \* Schedule: the name of the schedule instance will be used. \* int: the position of the experiment. \* None: if there is only one experiment, returns it.
**Returns**
A dictionary of results data for an experiment. The data depends on the backend it ran on and the settings of meas\_level, meas\_return and memory.
QASM backends return a dictionary of dictionary with the key counts and with the counts, with the second dictionary keys containing a string in hex format (`0x123`) and values equal to the number of times this outcome was measured.
Statevector backends return a dictionary with key statevector and values being a list\[list\[complex components]] list of 2^num\_qubits complex amplitudes. Where each complex number is represented as a 2 entry list for each component. For example, a list of \[0.5+1j, 0-1j] would be represented as \[\[0.5, 1], \[0, -1]].
Unitary backends return a dictionary with key unitary and values being a list\[list\[list\[complex components]]] list of 2^num\_qubits x 2^num\_qubits complex amplitudes in a two entry list for each component. For example if the amplitude is \[\[0.5+0j, 0-1j], …] the value returned will be \[\[\[0.5, 0], \[0, -1]], …].
The simulator backends also have an optional key snapshots which returns a dict of snapshots specified by the simulator backend. The value is of the form dict\[slot: dict\[str: array]] where the keys are the requested snapshot slots, and the values are a dictionary of the snapshots.
**Return type**
dict
**Raises**
**QiskitError** if data for the experiment could not be retrieved.

Create a new ExperimentResultData object from a dictionary.
**Parameters**
**data** (*dict*) A dictionary representing the Result to create. It will be in the same format as output by [`to_dict()`](qiskit.providers.ibmq.RunnerResult#to_dict "qiskit.providers.ibmq.RunnerResult.to_dict").

### get\_counts

Get the histogram data of an experiment.
**Parameters**
**experiment** (*str or* [*QuantumCircuit*](qiskit.circuit.QuantumCircuit "qiskit.circuit.QuantumCircuit") *or*[*Schedule*](qiskit.pulse.Schedule "qiskit.pulse.Schedule") *or int or None*) the index of the experiment, as specified by `data([experiment])`.
**Returns**
a dictionary or a list of dictionaries. A dictionary has the counts for each qubit with the keys containing a string in binary format and separated according to the registers in circuit (e.g. `0100 1110`). The string is little-endian (cr\[0] on the right hand side).
**Return type**
dict\[str, int] or list\[dict\[str, int]]
**Raises**
**QiskitError** if there are no counts for the experiment.

### get\_memory
<Function id="qiskit.providers.ibmq.RunnerResult.get_memory" signature="RunnerResult.get_memory(experiment=None)">
