  • Rating Methodology

    What Is the America’s Most Trusted® Study?

    The America’s Most Trusted® study focuses on evaluating brands that offer products or services to consumers in their homes, particularly in the residential new home industry. Instead of attempting to survey every brand, the study specifically targets the largest and most impactful brands in this sector.

    How Does the Survey Work?

    Conducted throughout the year, the America’s Most Trusted® survey aims to gather consumer opinions while minimizing biases that might arise from external events or trends. This year-long approach helps capture a more accurate snapshot of consumer sentiments.

    Participants are surveyed based on specific criteria, such as whether they are actively considering a purchase in a relevant category—like buying a home, faucet, HVAC. Only those who express familiarity with a brand are invited to share their opinions on its trustworthiness, ensuring that the study reflects genuine consumer insights.

    The Importance of Brand Awareness

    An essential component of the study is brand awareness. Participants are first asked to identify brands they recognize. Only those who are familiar with a brand proceed to answer questions about it. This criterion ensures that only brands with sufficient public recognition are included in the final trust rankings.

    Sampling Methodology

    The study employs a non-probability sampling design, relying on online panels to recruit participants. Online panels are organizations that have an established relationship with consumers who agree to complete opinion surveys. Lifestory randomly ask consumers questions that identify consumers shopping for a specific product. Qualified consumers complete an online survey in which they are asked a set of questions about specific product brands.

    The number of people completing a survey is referred to as the sample size. Each of the America’s Most Trusted studies seek to obtain a sample size that is large enough to be representative. The sample size is also designed to collect a large number of consumer opinions to minimize error and to assure the study results reflect the majority of consumers sentiment about a brand.

    Calculating Trust Scores

    At the heart of the America’s Most Trusted® study is the Net Trust Quotient Score. Participants evaluate brands based on their trustworthiness through a series of targeted questions. The responses are then categorized into three groups:

    • Advocates: Consumers who express strong trust in the brand.

    • Neutrals: Those who trust the brand but do not consider it superior to others.

    • Antagonists: Consumers with little to no trust in the brand.

    These evaluations are quantified using a statistical method called a z-score, which standardizes the responses, allowing for easy comparison across brands. The results are ultimately transformed into T scores, which are more intuitive for understanding how each brand ranks relative to the mean score of all brands surveyed.

Types of Smoke Detectors

A smoke detector is a vital safety device found in most homes, offices, and public buildings, designed to detect smoke or other signs of fire and alert people to potential danger. There are two primary types of smoke detectors: ionization smoke detectors and photoelectric smoke detectors, each using a different technology to detect smoke. Here’s an explanation of how both types work:

1. Ionization Smoke Detectors

How It Works: Ionization smoke detectors work based on the principle of detecting the disruption of an electrical current caused by the presence of smoke particles in the air.

  • Radioactive Source: Inside the detector, a small amount of radioactive material (usually americium-241) is placed between two electrodes. This radioactive material ionizes the air inside the detector, creating a flow of ions (charged particles) between the electrodes.

  • Electrical Current: The ionized air allows a small electrical current to flow between the electrodes.

  • Smoke Detection: When smoke particles enter the detector, they disrupt the flow of ions. Since smoke particles are electrically charged, they attach to the ions, which reduces the number of ions in the air. This disruption lowers the electrical current.

  • Alarm Activation: The detector senses this drop in the current and triggers the alarm to alert you to the presence of smoke.

Best For: Ionization smoke detectors are generally more sensitive to fast-flaming fires, which produce smaller, lighter smoke particles. They can detect the presence of smoke more quickly when there is little visible smoke.

2. Photoelectric Smoke Detectors

How It Works: Photoelectric smoke detectors work based on light scattering or light absorption. They use a light source and a sensor to detect smoke.

  • Light Source and Sensor: Inside the detector, there is a light-emitting diode (LED) and a light sensor placed at an angle. The LED is positioned to emit light across the interior of the sensor chamber, but the light does not directly reach the sensor.

  • Smoke Detection: When smoke particles enter the chamber, they scatter or absorb the light emitted by the LED. This scattered light then reaches the light sensor.

  • Alarm Activation: The sensor detects the change in light intensity and triggers the alarm, signaling the presence of smoke.

Best For: Photoelectric smoke detectors are more sensitive to smoldering fires, which produce larger smoke particles. These detectors tend to respond faster to fires that start with slow burning, like those caused by faulty wiring or overheated materials.

3. Combination Smoke Detectors (Dual-sensor)

Some modern smoke detectors combine both ionization and photoelectric technologies in one unit, which helps improve fire detection. These dual-sensor detectors can respond to a wider range of fire types, including both fast-flaming and slow-smoldering fires.
